Kunya-Urgench is situated in north-western Turkmenistan, on the left bank of the Amu Daria River. Urgench was the capital of the Khorezm region, part of the Achaemenid Empire. The old town contains a series of monuments mainly from the 11th to 16th centuries, including a mosque, the gates of a caravanserai, fortresses, mausoleums and a 60-m high minaret. The monuments testify to outstanding achievements in architecture and craftsmanship whose influence reached Iran and Afghanistan, and later the architecture of the Mogul Empire of 16th-century India.
