The foundations of the four-towered basilica dedicated to St Peter date from the 11th century and the side chapels are from the 1300s. But most of what you see today of the neo-Romanesque structure is the result of renovations carried out in 1881.
The most interesting parts of the basilica’s very ornate interior are the elevated central altar and four chapels under the towers and the crypt, the oldest part of the structure. The Chapel of Mary on the northwest side and the Chapel of the Sacred Heart to the northeast contain works by 19th-century painters Bertalan Székely and Károly Lotz. The Mór Chapel to the southeast has more works by Székely as well as magnificent pews. The Corpus Christi Chapel on the southwest side (enter from the outside) boasts a 16th-century red marble tabernacle, one of the best examples of Renaissance stonework in the country.
