Museum in Istanbul
The Istanbul Archaeological Museums are a complex of three museums in the first courtyard of Topkapi Palace: the main Archaeological Museum, the Museum of the Ancient Orient, and the Tiled Kiosk Museum. Entry is paid at a modest price. The Alexander Sarcophagus (not Alexander’s tomb, but one of the finest ancient sarcophagi in the world), the Treaty of Kadesh (the world’s oldest known peace treaty), and artifacts from Mesopotamia, Egypt, and Anatolia are here. Budget travelers pay the cheap ticket and see one of the top 10 archaeological collections on Earth.
