The construction of the mosque and complex in Hacı Bayram Square, which is considered sacred since the Phrygian period and is thought to have previously housed a temple dedicated to Cybele and Men, dates back to 1427-28. The building is dedicated to Hacı Bayram Veli, who lived in Ankara between 1352-1429, and was included on the UNESCO World Heritage List in 2016. The mosque and the complex were built to the southwest of the Temple of Augustus, also located in this square, without damaging the temple. The Hacı Bayram Veli Mosque and Complex is still a popular place of worship and a must-see in Ankara.
