Tihany Abbey, Benedictine abbey in Tihany, Hungary

Tihany Abbey is a Benedictine monastic complex in Baroque style at the eastern edge of the peninsula, with two towers rising above Balaton. The complex extends 46 meters in length and includes the church, a crypt, monastic cells, a refectory area, and a library.

King Andrew I founded the monastery in 1055, making it one of the oldest Christian religious institutions in medieval Hungary. The current Baroque design came from extensive reconstruction work during the 18th century.

The 1055 foundation charter, written on vellum and kept in the Pannonhalma Archabbey archive, is mostly Latin but preserves Hungarian words and phrases; the longest is feheruuaru rea meneh hodu utu rea, 'onto the military road leading to Fehérvár'. The abbey's patron saint, Bishop Aignan of Orléans, is honoured alongside the Virgin Mary.

The abbey museum opens Monday through Saturday and displays religious items with guided tours through the church and crypt. Access to the complex involves stairs, so mobility can be limited for some visitors.

The northwest tower holds a 1,670 kg bell, the largest in the Balatonfüred district. The southeast tower contains a 431 kg middle bell and a 227 kg smallest bell, the latter electrified but not regularly rung. During World War I two bells were requisitioned, and in World War II three of four bells were taken for military use.
