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 and is on the list of UNESCO World Heritage Site.
The first Benedictine monks settled here in 996. They went on to convert the Hungarians, to found the country’s first school and, in 1055, to write the first document in Hungarian. From the time of its founding, this monastic community has promoted culture throughout central Europe. Its 1,000-year history can be seen in the succession of architectural styles of the monastic buildings (the oldest dating from 1224), which still today house a school and the monastic community.
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 and the Archabbey Collection (the second biggest in the country).
