About this source

What it is

This is the mausoleum of the Seljuk ruler Ahmad Sanjar, built in 1157 in the city of Merv (now in Turkmenistan) by his successor. It is a large brick building shaped like a cube topped with a dome, built along the Silk Road. Today it stands, much restored, within the UNESCO World Heritage site of Ancient Merv.

Why it matters

Merv was one of the great cities of Central Asia. In 1221, Mongol forces led by Tolui, son of Genghis Khan, besieged and sacked the city, burning much of it, including this mausoleum, and causing great destruction and loss of life according to contemporary accounts. The ruined tomb is physical evidence of the scale of destruction the Mongol conquests brought to the cities of Khorasan, showing both the wealth of the civilization destroyed and the force used against it.
