The Tower of Toghrul was constructed in the 12th century to serve as a tomb for the Seljuk ruler Toghrul who died in 1063. Toghrul was the founder of the Seljuk Empire, which spanned from modern day Turkey to Afghanistan. The tower originally had a dome at its top, which collapsed during an earthquake. Today the tower is 20 meters tall (66 ft.)."
