Itchan Kala east gate

The Polvon Gate is the eastern gate of the Itchan Kala fortress in Khiva (1806). The people also call it Poshshob (Jallod) Gate or Slave Gate. It is the main entrance to Khiva, Uzbekistan. It was built by seven craftsmen under the supervision of a master builder. A canal that brought water from the Amu Darya river surrounded the fortress wall. The gate had a bridge that could be lifted at night. Polvon Gate's master builder received the same salary as the master builder who worked at the Ark Gate, the gate of the Khiva Khan's palace. The current appearance of Polvon Gate is the result of several renovations. Previously, the gate protruded slightly outward from the fortress wall. It had a watchtower on top that allowed to observe the outside of the city. The gate was rebuilt in 1806 under Iltazar Khan from baked bricks. In addition, a long corridor – a vault was also built, which served as a place for trade stalls. The towers on the side of the gate were connected to the city wall. After the construction of the caravanserai and the covered bazaar in 1832–1833, the gate lost its role as a market. In 1835, the Olloqulixon Madrasa was built inside the gate, and its western part was rebuilt. A new bathhouse with two domes and a portal was built in front of it. The inner courtyard was enlarged as a result of the construction of the Olloqulixon Madrasa. It was also called the “Flower
