The Benedictine Pannonhalma Archabbey or Territorial Abbey of Pannonhalma (lat. Archiabbatia or Abbatia Territorialis Sancti Martini in Monte Pannoniae) is a medieval building in Pannonhalma, one of the oldest historical monuments in Hungary. Founded in 996, it is located near 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 (), from which the monastery occasionally took the alternative name of Márton-hegyi Apátság. This is the second largest territorial abbey in the world, after the one in Monte Cassino. Its sights include the Basilica with the Crypt (built in the 13th century), the Cloisters, the monumental Library with 360,000 volumes, the Baroque Refectory (with several examples of trompe-l'œil) and the Archabbey Collection (the second biggest in the country). Today there are about 50 monks living in the monastery. The abbey is supplemented by the Benedictine High School, a boys' boarding school. History It was founded as the first Hungarian Benedictine monastery in 996 by Prince Géza, who designated this as a place for the monks to settle, and then it soon became the centre of the Benedictine order. The monastery was built in honour of Saint Martin of Tours. Géza's son, King Stephen I donated estates and privileges to the monastery. Astrik (Anastasius) served as its first abbot. The oldest surviving document to use the Hungarian language, the Charter of the Tihany Benedictine Abbey, dating back to 1055, is still preserved in the library. In 1096, on his way to the holy lands as leader of one of three crusader armies, Duke Godfrey of Bouillon spent a week here negotiating his army's safe passage through Hungary from king Coloman. The first buildings of the community were destroyed in 1137, then rebuilt. The Basilica's pillars and the early Gothic vault were built in the early 13th century, using the walls of the former church. In 1486, the abbey was reconstructed under King Matthias in the Gothic style. The monastery became an archabbey in 1541, and as a result of Ottoman incursions into Europe in the 16th and 17th centuries it was fortified. During one and a half centuries of the Turkish Occupation, the monks, however, had to abandon the abbey for shorter or longer periods of time. Only later were they able to start the reconstruction of the
