King Béla III. established a cistercian abbey in Pásztón in 1190. The cistercians took the buildings of the former benedictine abbey and in the first third of the 13th century they extended and reconstructed the sanctuary of the church.

In the cellar of the schoolmaster's house we can see an exhibition demonstrating the medieval vine cultivation. Vine growing and wine production was flourishing in the vicinity of the town, but a pestilence at the end of the 19th century put an end to it all. In the gothic cellar of the schoolmaster's house we can see all kinds of vine-growing instruments.
