Juma Mosque Khoja Ahror Vali (Djami Mosque) Juma Mosque Khoja Ahror Vali is a basis of the ensemble Registan which is located near Chorsu square. It is a unique Friday mosque in Tashkent of courtyard type among existed ones in Central Asia in times of late Middle Ages. The main building is a cubic volume blocked by a dome with four windows in a low drum. The eastern wall which is directed into the yard is cut through by a big arch.

The basis of the mosque was put in the IXth century, followed by the Arab conquest of ancient Tashkent, in those times it was called by Chach. Ubaydulla Khoja Ahror arrived in Tashkent in 1432, a famous public figure of the Timurid era. Khoja Ahror ordered to erect a considerable Friday mosque and madrasah in ancient Tashkent mahalla Gulbazar. So, on the old basis which remained from the first Tashkent mosque of Yahya ibn Asad period, in the middle of the XVth century appeared a peculiar cube with a dome and with an open arch overlapping on the east region.

In 1888 the mosque was restored on means of the Russian emperor Alexander III so was named as "Tsar's mosque". Notably, it is the third-largest Friday mosque in Uzbekistan. It yields only to Bibi-Khanym in Samarkand and Kalyan in Bukhara.
