Persepolis
The ceremonial capital of the Achaemenid Persian Empire/World Landmarks
Persepolis (Takht-e Jamshid) in modern Iran was the ceremonial capital of the Achaemenid Empire, founded by Darius I around 515 BC. Built on a massive stone terrace 455 m by 300 m, the complex included the Apadana (audience hall) with 72 columns each standing 19 m tall, the Gate of All Nations, and the Throne Hall (Hall of Hundred Columns). Alexander the Great burned Persepolis in 330 BC, but the ruins remain one of the most impressive archaeological sites in the world.
