Southeast of Gölbaşı is the Dergah complex of mosques and parks surrounding the colonnaded courtyard of the Hazreti İbrahim Halilullah, built and rebuilt over the centuries as a place of pilgrimage. To visit these important places of worship you should be modestly dressed. Its western side is marked by the Mevlid-i Halil Camii, a large Ottoman-style mosque. At its southern side is the entrance to the cave where Abraham was reputedly born.
