The Blue Mosque is a mosque located in the center of Mazar-i-Sharif, Afghanistan.
The Seljuq dynasty sultan Ahmed Sanjar built the first known shrine at this location. It was destroyed or hidden under earthen embankment during the invasion of Genghis Khan in around 1220. In the 15th century, Sultan Husayn Mirza Bayqarah built the current Blue Mosque here. It is by far the most important landmark in Mazar-i-Sharif and it is believed that the name of city (Noble Shrine, Grave of Sharif) originates from this shrine.
