St. Peter and Paul's Cathedral Basilica or simple Pécs Cathedral is one of the most beautiful cathedrals in Hungary. There is evidence that in this place stod an early Christian Roman basilica from the 4th century when Christianity spread through the Roman Empire. During its existence, the cathedral has been remodeled several times. After the Ottoman conquests, it was a mosque for a few decades. The cathedral got its present appearance after extensive reconstructions completed in 1891 under the supervision of the architect Friedrich von Schmidt. After the visit of Pope John Paul II in 1990, significant efforts were made to preserve Romanesque carvings and sculptures. The project was completed in 2004, and the result is the largest exhibition of Romanesque carvings and sculptures in Central Europe.
