The Kharraqan towers are mausoleums, built in 1093 CE and 1067 CE, located on the plains in northern Iran, near Qazvin.
The brick structures stand 15 meters tall and 4 meters wide, and make extensive use of geometry. Inside the older mausoleum there is a lamp and paintings.
These are remnant examples of architecture that exist from the Seljuk dynasty of medieval Persia.
Both towers were significantly damaged by the 2002 Bou'in-Zahra earthquake. These were in a good state of preservation prior to the rupture, suggesting it was one of the most powerful in the region for approximately 900 years.
