Restored by architect Mimar Sinan in the 16th century, with Kütahya tiles being added in the 18th century. Just next door is the small tomb of Hacı Bayram Veli, a poet and Sufi, who settled in Ankara in the 15th century to spread his teachings. This is considered to be the holiest shrine in the city by pious Muslims, who can be found praying in and outside the tomb in large numbers regardless of the time of the day. Take a look inside to see the colourful dome topping the structure.
