Osman Shah Mosque ( ) or Kursum Mosque (Κουρσούμ Τζαμί, from ) is a 16th-century Ottoman mosque in the city of Trikala in Greece .1 The mosque was commissioned by Osman Shah, also known as Kara Osman Pasha, who was the son of one of Sultan Selim I 's daughters and the executed vizier İskender Pasha (died 1515). Osman Shah for a long time dwelt in Trikala as the governor of the local province, the Sanjak of Trikala . The mosque was designed by the Ottoman imperial architect Mimar Sinan and is the only one that he designed in modern Greece. The exact dating of the mosque is uncertain, but it was probably built in the period 1550–60, most likely in the late 1550s. Osman attached several charitable establishments to the mosque, among others a madrasah , an alms house, and a caravanserai , and was himself buried in a türbe in the mosque's southern courtyard at the time of his death in 1567/8. By the time of Evliya Çelebi 's visit a century later, the mosque was the principal mosque of the city. It is also the only mosque still standing in the city of Trikala out of the at least eight that Evliya Çelebi reported seeing. The building itself consists of a square prayer hall topped by a large 18 metres (59 ft) diameter semi-spherical dome. The portico ( revak ) in front, was completely rebuilt in the renovations carried out in 1998. The ashlar minaret is located on the northwestern corner and is well preserved, except for its missing roof. All other buildings attached to the mosque have since vanished, except for the founder's octagonal türbe , which is used as a storage site for artefacts recovered from archaeological excavations. The mosque is no longer used for worship; it now functions as a venue for minor events and is a protected UNESCO site. Hellenic Ministry of Culture . E. ; van Donzel, E. & Heinrichs, W.2
