A general overview of Ottoman architecture
Ottoman architecture is divided into several distinct periods: the Early Period, the Classical Period, the Tulip Age, the Westernization Period (which includes Baroque, Rococo, and Empire styles), and the First National Architecture Movement. Each period reflects changes in aesthetic concepts and stylistic developments in architectural works. While structures from the early period are mainly found in İznik, Bursa, and Edirne, those from the Classical period and later are primarily located in Istanbul.
Early period Ottoman architecture
Also referred to as the Bursa style in some sources — due to the monumental structures built in Bursa, the early capital of the Ottoman State— early period Ottoman architecture spans from the foundation of the state to the start of construction of the Bayezid Mosque. According to some researchers, this period ended with the completion of the Üç Şerefeli Mosque in Edirne, during which the foundations were laid for ideas such as the use of domes, which would define the Classical period.
After conquering Istanbul, Fatih Sultan Mehmet launched a major reconstruction in the city, and the capital was moved from Edirne to Istanbul. Instead of the Old Palace in Edirne, a new palace was built in Istanbul at Beyazıt Square. During this period, construction of the Fatih Complex and Topkapı Palace also began. The Fatih Mosque, which was destroyed in the earthquake of 1766, was rebuilt in 1771 and has retained its current form ever since. One notable work from this era is the Tiled Kiosk (“Çinili Köşk”), originally built as the summer palace of Topkapı Palace and now part of the Istanbul Archaeology Museums. The mosaic tiles covering the entrance iwan on the kiosk’s exterior facade are the last traces that carry on the Seljuk-era tradition. The Kiosk is also worth visiting because it was built under Seljuk influence and stands as one of the early examples of Ottoman civil architecture in Istanbul.
Classical period
In Ottoman architecture, the 15th century, known as the Classical period, is sometimes divided into the Early Classical Period, the Mimar Sinan Period, and the Late Classical Period by different sources. During this time, Mimar Sinan designed some of Istanbul’s most iconic buildings, including the Süleymaniye Mosque, the Şehzade Mosque, and the Mihrimah Sultan Mosque. The Blue Mosque, renowned for its blue tiles and regarded as the last major mosque of the Classical Period, was also built toward the end of this era by Sedefkâr Mehmed Ağa. The New Mosque, constructed during the same period and regarded as the last great work by the generation trained in the Mimar Sinan style, still overlooks the Golden Horn from the Eminönü side of the Galata Bridge today. To see the Blue Mosque in person, you can book a flight to Istanbul right away.
To discover mosques from different eras across the city — from the Blue Mosque to Süleymaniye, from the New Mosque to Eyüp Sultan — check out our article on Istanbul’s mosques. Construction of the New Mosque, located right on the waterfront in Eminönü, began during the reign of Safiye Sultan. However, the project was left unfinished following the deaths of the architect, then Mehmed III, and finally Safiye Sultan herself. The structure gradually deteriorated over time and was further damaged in the great fire of 1660. While touring the city to aid the public after the fire, Turhan Sultan came across the abandoned construction site and, already intending to commission a mosque of her own, decided to complete this one. The last of the grand mosques commissioned by the Ottoman dynasty in Istanbul, the New Mosque was built alongside the Hünkâr Pavilion and the Spice Bazaar arcade.
The domed central plan — an architectural layout in which the entire space is organized around a single large central dome — became the most widely used style of this period. In this plan, frequently employed by Mimar Sinan, structural elements that obstructed the view inside were removed and replaced with columns that supported the space without dividing it.
Tulip Age
The Tulip Age refers to the period between 1718 and 1730 in the Ottoman State. The tulip, the favorite flower of the era’s ruler, Sultan Ahmed III, saw its cultivation become increasingly popular during these years, giving the period its name. During this time, decorative changes were favored in architecture rather than changes to the actual space. The vases decorated with fruit and floral motifs, now seen in museums, became some of the most popular decorative items of the period, and the tulip motif was frequently used in tiles and ornamentation.
Another defining feature of this period is the emphasis placed on civil architecture. Ornate monumental public fountains replaced the earlier wall-mounted fountains, where functionality had been the priority. The lavishly decorated waterfront mansions, palaces, pavilions, and summer residences built along the Bosphorus shores and in Sadabad (present-day Kağıthane) represent examples of Tulip Age residential architecture. Because they were built of wood, many of these structures no longer stand today, though the Aynalıkavak Pavilion and the Library of Ahmed III inside Topkapı Palace are among those you can still visit.
During this period, the wide eaves on buildings provided protection from sun and rain while adding an aesthetic touch, and curved, dynamic lines replaced the sharp, geometric lines of the Classical period. The most famous work of the Tulip Age today is the Fountain of Ahmed III, located at the entrance to Topkapı Palace; this fountain is also one of the earliest examples of the Rococo architectural style in the Ottoman State. The white marble that gleams in the sunlight, the colorful stones, and the gold-leaf ornaments symbolize the era’s spirit of splendor and luxury.
Westernization period (Baroque, Rococo, Empire)
By the 18th century, the effects of Westernization had become visible in Ottoman architecture. Styles like Baroque and Rococo, which originated in Europe in the early 17th century, were incorporated into Ottoman architecture by the early 18th century. While the Baroque style emphasizes grandeur, exaggeration, and movement, Rococo features a more elegant, lightweight, and asymmetrical design. Notable examples of the Baroque period include the Nuruosmaniye Mosque and the Laleli Mosque, known for their circular and flowing lines. The Nuruosmaniye Mosque, the first and largest example of the Baroque style in the Ottoman State, is also the first mosque to feature a semicircular courtyard. The Laleli Mosque, with its curvilinear design elements in the shapes of C and S, reflects the dynamic architectural spirit of the era by combining it with the Rococo style. For Rococo, the interior motifs of the Büyük Mecidiye (“Ortaköy”) Mosque, Dolmabahçe Palace, and some waterfront mansions are good examples. Generally used in combination with the Baroque style, Rococo was predominantly applied in interior décor and ornamentation.
The Empire style, which was used in Istanbul alongside Baroque and Rococo, first appeared in the Nusretiye (Tophane) Mosque. The most notable representatives of this style were the Balyan family, whose signature can be seen on many magnificent works in the city, including Dolmabahçe Palace and the Büyük Mecidiye Mosque.
Three overarching characteristics can be observed throughout the Westernization period. The first is the replacement of tile art, which had been used extensively in the Classical period, with stone carving, marble reliefs, and painted wall murals. In addition, brighter interiors were created; windows were designed to be larger and more frequent than before, making interior spaces airier and more luminous. Finally, building entrances were elevated with staircases and monumental gates were constructed. These differences can be easily seen when comparing the Rüstem Pasha Mosque with the Büyük Mecidiye Mosque, or Topkapı Palace with Dolmabahçe Palace.
National Architecture Movement
The final phase of Ottoman architecture also marked a new beginning. Bolstered by the declaration of the Second Constitutional Monarchy in 1908, nationalism started to influence architecture as well, leading to the emergence of the First National Architecture Movement as a response to the eclectic style of foreign architects. Led by Mimar Kemaleddin Bey and Vedat Tek, this movement sought to reinterpret the decorative features of Seljuk and Classical Ottoman architecture within modern structures.
Among the most notable examples in Istanbul is the Sirkeci Grand Post Office, designed by Vedat Tek and considered the first building of the movement. With its grand entrance façade, pointed arched windows, and tile decorations, the building clearly pays homage to the Ottoman past. The Harikzedegan (Tayyare) Apartments in Laleli, designed by Mimar Kemaleddin Bey, are among Istanbul’s first reinforced concrete structures and are now operated as a hotel. The same architect’s Kemer Hatun Mosque and the Fourth Vakıf Han are also recognized as important examples of the movement in Istanbul. The Beşiktaş Ferry Terminal, designed by Ali Talat Bey, remains another graceful work from this period along the shores of the Bosphorus.
The master architects of the Ottoman era
Mimar Sinan
Born in Kayseri in the 15th century, Sinan was brought to Istanbul as a devshirme recruit during the reign of Yavuz Sultan Selim and took part in the campaigns of Kanuni Sultan Süleyman during his years in the military. During this time, Sinan traveled to different parts of the state— from Rhodes to Mohács, from Belgrade to Baghdad — and had the opportunity to study the architecture in these regions up close.
Mimar Sinan, the most prominent figure of Ottoman Classical Period architecture, is known to have influenced many architects who came after him through his works. As he described it himself, the Prince’s Mosque (Şehzade Mosque), which he called his “apprenticeship work,” and the Süleymaniye Mosque, which he regarded as his “journeyman work,” both adorn the historic skyline of Istanbul. To learn more about Mimar Sinan’s life and the works he shaped with his architectural genius, read our article Mimar Sinan: The brilliant architect who built an era.
Along with masterpieces like the Selimiye Mosque in Edirne, the famous architect created over 300 works scattered throughout the state. Notable examples include the Rüstem Pasha Mosque in Istanbul’s Tahtakale district, known for its blue decorations; the Mağlova Kemer Aqueduct over the Alibey Stream; and the Kanuni Sultan Süleyman Bridge, which is at the point where Büyükçekmece Lake meets the Sea of Marmara.
The Rüstem Pasha Mosque was built as a “fevkani” structure — meaning it was raised on an elevated platform — with shops placed underneath. While it appears quite plain from the outside, the interior features some of the finest and most accomplished tile work of its era. Because the quantity of tiles used was so great, the tile workshops in İznik could not keep up with demand, and additional workshops were established in Kütahya to supply tiles for the mosque.
The Mağlova Aqueduct, also known as Muallakkemer, is considered one of the masterpieces of water architecture. A two-tiered arch that forms part of the Kırkçeşme water system bringing water to Istanbul, it is approximately 260 meters long and still carries water to the city today. The Mağlova Aqueduct, also known as Muallakkemer, is considered one of the masterpieces of water architecture.

Balyan Family
In the late Ottoman period, the Balyan family, who built many structures in the city, developed a new eclectic style called Turkish Baroque Architecture by blending the Baroque style with traditional Ottoman architecture. Their work across five generations includes the Dolmabahçe, Çırağan, and Beylerbeyi Palaces; the Küçüksu and Ihlamur Pavilions; and the Büyük Mecidiye, Nusretiye, and Pertevniyal Valide Sultan Mosques.
As palace architects with their signature on numerous structures across Istanbul, the family built not only the waterfront palaces that defined the city’s 19th-century silhouette but also religious and public buildings. Combining elements of traditional Turkish architecture with the education they received in Europe, the family produced their most important works during the reigns of Sultan Abdülmecid and Sultan Abdülaziz, serving not only as architectural designers but also as engineers and urban planners.
Alexandre Vallaury
Alexandre Vallaury, an Istanbul-based architect of French origin, stands out as an important figure in 19th-century Ottoman architecture. Also a painter, Vallaury met Osman Hamdi Bey, another renowned painter of the period, and established the architecture department at the School of Fine Arts (Sanayi-i Nefise School), which his art-loving friend founded. Vallaury later built many works across the city and received the title Architect of the City (Mimar-ı Şehir). Many of his buildings can be seen around Pera and Beyoğlu; the Ottoman Bank building (now Salt Galata), Pera Palace Hotel, the Istanbul Archaeology Museum, and Union Française are just a few.
Vallaury is known for combining multiple architectural styles, blending what he learned at the École des Beaux-Arts in Paris with the neoclassical architecture of Europe and the Orientalist elements of the East. One of the finest examples of this approach is the Ottoman Bank building in Karaköy. Now serving as a museum, the building’s street-facing side was designed in a neoclassical style, while its Golden Horn-facing façade was given an Orientalist treatment. The other buildings on the same street were constructed in a similar style, giving rise to the famous Bankalar Caddesi (Banks Street).
Unique Ottoman works of Istanbul
Istanbul’s Ottoman architectural heritage extends beyond mosques and palaces. The city’s unique geography and strategic location have also given rise to architectural works you won’t find anywhere else.
Rumeli Fortress
Perched at the narrowest point of the Bosphorus, directly opposite Anadolu Fortress, Rumeli Fortress stands as one of the most impressive examples of Ottoman military architecture. Just a year before Istanbul’s conquest, in 1452, Fatih Sultan Mehmet ordered the construction of this massive fortress to block aid ships from passing through the Bosphorus. The building of its three large towers was assigned to Saruca Pasha, Zağanos Pasha, and Halil Pasha. Completed in an astonishingly short span of about four months, the fortress features some of the largest bastions of its era. Today, serving as a museum, Rumeli Fortress is also one of Istanbul’s top spots for photography, thanks to its silhouette set against the Bosphorus view.
Grand Bazaar
The Grand Bazaar, which began to take shape around two covered market halls (“bedesten”) during the reign of Fatih Sultan Mehmet, expanded over centuries to become one of the oldest and largest covered bazaars in the world. Spanning more than 30,000 square meters, the bazaar has over 60 streets and thousands of shops. With its vaulted ceilings, stone arches, and maze-like street layout, the Grand Bazaar stands out as a unique example of Ottoman commercial architecture. Operating continuously for hundreds of years, this structure is not only a shopping center but also a living architectural monument.
Waterfront mansions on the Bosphorus
The wooden and masonry waterfront mansions that adorn both shores of the Bosphorus represent a unique architectural style specific to Istanbul. Built during the Ottoman period for members of the imperial family and high-ranking officials, these seaside residences reflect a lifestyle closely connected to the sea. The Amcazade Hüseyin Pasha Mansion in Anadolu Hisarı, dating back to the 17th century, holds significance as one of the oldest surviving Ottoman civil structures in Istanbul. Along the shoreline from Kuzguncuk to Bebek and from Çengelköy to Kandilli, waterfront mansions from different periods continue to be an integral part of the Bosphorus landscape. To get to know these elegant structures on both sides of the Bosphorus more closely, read our article on waterfront mansions of the Bosphorus.
From the Seljuk-influenced pavilions of the early period to the magnificent mosques of the classical era, from the elegant fountains of the Tulip Age to the grand palaces of the Westernization Period, Istanbul showcases every phase of Ottoman architecture like an open-air museum. These structures are more than just stone and marble; each one reflects the political climate, aesthetic views, and social changes of its time. On your next trip to Istanbul, don’t just look at these landmarks — take a moment to listen to the stories behind them.
