Alaaddin Hill in the Karatay district of Konya is one of the most important prehistoric settlements. This hill's importance in art history, architectural history, archaeology, and historical science is endless. It is said that when Konya was the capital of the Seljuk Empire, Sultan Alaaddin asked the people to build a hill in the city's center to build a mosque. So, everyone in the town brought soil to the city's center and created this hill. Alaaddin Mosque, one of the most important historical monuments that has survived today, is located on the hill. Alaaddin Mosque was built during the reign of the Great Seljuk Sultan Alaaddin Keykubat on the site of Konya's old castle from 1221 and today dominates the Konya skyline. On one side of the mosque are the ruins of the Seljuk Imperial Palace.
