Kalyan Minaret has a Twin: in the middle of the 12^th century, a talented pupil of Bako constructed a similar minaret in Vabkent, located not far from Bukhara. It is a well-balanced brick tower, 39 meters in height. Vabkent Minaret is also crowned with a fine arch, named "light" analogous to a lighthouse ("minaret" comes from the Arabian "manara" — a place of fire, lighthouse). The scale and harmony of the two Bukhara minarets determined the value and status of the minaret in Central Asian architecture, as a symbol of its Islamic culture.
