The one-time Pasha Gazi Kassim Mosque is now the Inner Town Parish Church (Belvárosi plébánia templom), but it's more commonly referred to as the Mosque Church. It is the largest building from the time of the Turkish occupation still standing in Hungary and the very symbol of Pécs.
Turks built the square mosque with its green copper dome in the mid-16th century with the stones of the ruined Gothic Church of St Bertalan. The Catholics moved back in the early 18th century, and the northern semicircular part was added in the 20th century. The Islamic elements on the south side are easy to spot: windows with distinctive Turkish ogee arches; a mihrab (prayer niche) carved into the southeast wall; faded verses from the Koran to the southwest; and lovely geometric frescoes on the corners. The mosque’s minaret was pulled down in 1753 and replaced with a bell tower; bells are rung at noon and 7pm.
