Medieval Bukhara was known as a business city receiving merchants from Central Asia, Iran and India, Russia and China. Central streets served as markets, each of which specialized in different product. So, domed and multi-arched buildings were constructed in squares and crossroads to make sale more comfortable. They were named 'tok' - arch, dome.
