Hisar Fortress is the ex-residence of Bek — a deputy of Bukhara emir. The fortress walls were 1 meter thick and had gun slots for rifles and cannons. Inside of the fort was garden and water pool. Stairs and brick terraces were lead to the main entrance. Unfortunately they were lost with time as well as the palace building. The only part that remains till our days is monumental gates built of burnt bricks with two cylinder towers and lancet arch between them. This type of architecture is typical for most of Bukhara buildings built within XVIII-XIX cc.
Across the gates was marketplace with caravanserai and numerous shops. Another buildings around square include old madrassah built in XVII. New madrassah buit in XVIII-XIX cc and mausoleum of XVI c. Both Madrassahs are built of brick and topped with domes. Inside is a wide area with cells built along the inner walls. In the beginning of XX century madrassahs host about 150 students and were closed by 1921.
Another notable construction in Hisar Fortress is «Hishtin» Caravan Serai, built in XVII cc. Hishtin is Persian for «built of brick». By XX century there were only remnants of foundation and wall sections of 1m high. Only a single photo taken in 1913 helped to restore it. Stone mosque — walls of up to the half of it’s height indeed were built of stone in XII c. The unique feature of the building are 4 resonators immured into the inner space of the pre dome constructions made of 4 jugs without bottoms and served to improve room’s acoustics where praying and sermons were read.
