Monastery of St Lawrence at Buda, Church ruin and monastery in Budapest District II, Hungary.

The Monastery of St Lawrence at Buda lies in the Szépjuhászné saddle between Hárshegy and János Hill in Budapest's 2nd district. Excavations by Imre Henszlmann (1847), Sándor Garády (1934) and László Zolnay (1961–1985) uncovered the foundation walls of a single-nave church with a rib-vaulted polygonal sanctuary, a rectangular cloister around a 10 x 15 m courtyard, and a chapter house with a priors' chapel.

The monastery was founded by Pauline monks in the early 14th century and grew into one of medieval Hungary's foremost religious centers. It was destroyed during the Ottoman advance of 1526 and was never rebuilt.

The site drew pilgrims from across the region who came to venerate its sacred relics and participate in religious devotion. Local monks maintained a center of learning where important religious texts were copied and translated.

The site is on a hillside and reached on foot, so sturdy shoes are a good idea given the uneven ground. Some of the recovered carved stones have been built into nearby structures where they can be seen more closely.

In 1381, relics of St Paul were brought here from Venice, turning the site into the most important Pauline pilgrimage destination north of Rome. The Pauline Order, the only monastic order of Hungarian origin, chose this place as its spiritual heart.
