The most interesting part of the church interior is the High Altar on which the Assumption is placed. It was painted by Maulbertsch in 1754 and purchased later for the church at Zirc. The monumental painting is flanked by pairs of statues: Sts Benedict and Bernard, and among the columns, Sts John the Baptist and Joseph. The High Altar was carved at Pápa and set up in 1755.
