Aslanhane (Ahi Şerafettin) Mosque The Aslanhane Mosque is one of Turkey's oldest mosques and was constructed in 1290 during the reign of the Anatolian Seljuks. It is situated next to the Ankara citadel and is named after Ahi Şerafettin, whose tomb is located opposite the mosque. The mosque is also commonly known as the "house of the lion" due to the lion statue on the ancient marble wall of Ahi Şerafettin's tomb. The mosque is a square-shaped building with an area of 400 square meters and features one minaret. The roof is made of wood and is supported by 24 large wooden columns. The mihrab, which indicates the direction of Mecca for prayer, is decorated with Seljuk tiles from earlier buildings. The mosque's construction material primarily consists of spolia from existing structures, and it has three gates and 12 windows within its walls.
