The 11th-century rotunda features the arched altar carved into the eastern wall, a gate to a residential tower on the north side, and an outer gate to the east. The 11th-century tombs in the bottom of the tower and the 13th-16th-century ones in the front of the altar are the burial places for the Nádasdy family. The residential towers offers view to north-east and north-west direction to the Rába River valley, toward southern and western directions one can see the roads of Hegyhát, while the northern direction offers the sight of the Kőszeg and Styrian mountains. The rotunda was destroyed in 1664 by the Turkish army advancing to the battle near Szentgotthárd.
