In the 12th century, during the reign of the Karakhanid dynasty in a place of destroyed small minaret was erected another, called the Kalyan minaret, which in Persian meant “great minaret”. It was indeed the largest building in Bukhara – it reached the height of 46.5 meters. Near the same minaret was built the Kalyan mosque, which in consequence was completely destroyed by Genghis Khan. In the early 15th century, the ruler of Sheibanids dynasty rebuilt the mosque again. Still preserved the lower walls from the former mosque. Today the Kalyan mosque is the largest mosque after the Bibi-Khanum mosque in Samarkand. This majestic mosque can accommodate 12,000 people.
The Kalyan mosque is not only a Holy place for Muslims, but also historically important architectural structure. Its walls are decorated with ornaments and mosaics and the sacred words from the Quran –traced out golden painting. This mosque is one of the oldest mosques and the second largest in Central Asia.
The artistic decoration of the mosque is amazing –carved mosaics decorating with high portal and inner dome never ceases to impress. The dome of the Kalyan mosque towers over buildings in the city and is bathing in blue Bukhara sky.
