Poi-Kalyan ensemble consists of Kaylan mosque, Kalyan Minaret and Mir Arab Madrasah. Frist walls of this ensemble were built in 713. This period concurred with the invasion of Arabs and the beginning of influence by Islamic culture. This is the rreason why the ensemble is so unique in its nature. The translation into English means “footsteps of the great”. The words reflect the real situation since its main building – Kalyan Minaret is seen almost from any angle of Bukhara.
