The Polvon Gate is the most elaborate of Khiva's four gates, with two domed chambers flanking a central passage and a brick portal above. The 1806 construction is part of Allakuli Khan's wider rebuilding of the eastern walls, and the gate originally controlled all overland traffic from Urgench and Bukhara.
A small museum in the gate chambers covers the slave trade and its abolition by the Russians, with photographs and a few surviving objects. Step through to the outer side for a view back at the walls and the new town beyond.
