Djumaya Mosque, known also as Ulu Mosque, is a precious architectural monument in the center of Plovdiv. It is one of the biggest and the oldest mosques in Bulgaria. It is called Djumaya (from Turkish – Friday), because the service was held in Friday.

     It is believed to be built as an imperial mosque by Shihabedin pasha, son of the patron of Plovdiv and beilerbei of Roumelia, during the reign of Murad II (1359 – 85). The building has been restored twice: in 1785 and again in 1818 after being damaged in an earthquake.

Its 23 meter high minaret decorated with zigzag lines rises from the Northeastern corner of the mosque, while diagonally, in the southeastern corner, there is an ancient sun-dial.

     It is said to be one of the three examples of the oldest type of the Ottoman worship buildings still preserved on the entire Balkan.
