The Colosseum, Rome

Any list of the world’s most interesting architectural structures will include Rome’s Colosseum. Erected under the Flavian emperors — and thus also known as the Flavian Amphitheatre — the Colosseum’s construction began sometime around 70 CE, during the reign of Vespasian. This dramatic emblem of Rome’s glorious past was built on the site of Nero’s “golden palace”, where the grandiose artificial lake was drained to make room for an amphitheater that could accommodate up to 50,000 spectators. The Colosseum’s design was equally innovative: A freestanding structure made from stone and concrete, the Colosseum rose more than three stories and featured a retractable awning to shield the audience during sunny days.

Also known as the “Underground Mosque”, the austere Sancaklar Mosque was designed by architect Emre Arolat and features a sloping terrain that gives the impression of being underground. Following such a path has a spiritual significance beyond architecture: it emphasizes that those who visit the mosque to worship leave the outside world behind as they descend the stairs and become one with the earth.
