Pannonhalma's most notable landmark, the Benedictine Pannonhalma Archabbey, one of the oldest historical monuments in Hungary, can be found next to the town, on top of a hill (282 m). Saint Martin of Tours is believed to have been born at the foot of this hill, hence its former name, Mount of Saint Martin (Márton-hegy in Hungarian), from which the monastery occasionally took the alternative name of Márton-hegyi Apátság. This is the second largest territorial (ie., approx. sovereign) abbey in the world, after the one in Monte Cassino.
