The Registan (Uzbek: Регистон, Registon) was the heart of the ancient city of Samarkand of the Timurid Empire, now in Uzbekistan. The name Rēgistan (ریگستان) means "sandy place" or "desert" in Persian.
The Registan was a public square, where people gathered to hear royal proclamations, heralded by blasts on enormous copper pipes called dzharchis - and a place of public executions. It is framed by three madrasahs (Islamic schools) of distinctive Islamic architecture. The square was regarded as the hub of the Timurid Renaissance.
