The western gates lead to the first castle of the city, Kunya Arch. It was built by the Khiva Khan Muhammad Erenk Khan in the 17 century. By the end of the 18 century, Kunya Arch was separated from Ichan Kala and became a city. Like other cities, it had the Khan mosque, the Khan residence, the court, the Khan hall called Kurinish Khana, several military factories and buildings, the mint, the chancellery, the Khan private residence, the kitchens, the stables, and other attributes of the city.
The throne of the Khan was in the veranda consisting of two grand columns in the south part of the Khan Hall. The tent, where the Khan received the guests, was raised in the middle of the Hall. The western part of the Hall had the Khan treasury and the manuscripts archive. The veranda was decorated with majolica in blue, white colors and fascinating ornaments.
