Ferhadija Mosque in Sarajevo (Bosnian: Ferhat-pašina džamija, Turkish: Ferhad Paşa Camii), also known as Ferhat-Pasha Mosque, is a central building in the city of Sarajevo built by Bosnian Sanjak-bey (governor) Ferhad-Beg Vuković, a descendant of the famous mediaeval Vuković-Desisalić family. This mosque has one dome above the prayer area (namaz) and three small domes at the cloister and is one of the greatest achievements of Bosnia and Herzegovina’s 16th century Ottoman and Islamic architecture. The Ferhadija mosque reflects the full maturity of the classical Ottoman style-domed mosque, portico with small domes, and beautiful built-on minaret. Research works on the painted decoration inside the mosque carried out in the 1964/1965 revealed five painted layers dating from various periods. The oldest and extremely valuable decorations of the first layer date from 16th century (in the dome, on the cornice and pendentives, the base of the corner calottes, the mihrab and the lunettes of the lower row of windows), belonging to the group known as Rumi ornament,m which were also to be seen in the Aladža mosque in Foča.
