It had to be rebuilt when the Prince-Bishop of Würzburg, John II of Brunn, elevated the old chapel to become the parish church of the village. The chapel was dedicated to St. Nicholas and the Blessed Virgin Mary. By 1563, however, it was decided to build a separate parish church on a plateau in front of the castle gate. This building was demolished in 1908/09 in favour of the surviving neo-Romanesque church, but it is well documented in the 1916 inventory volume. The chapel comprised a rectangular nave with an attached choir with net vaulting (Netzgewölbe) at the eastern end. The nave rests on the barrel vault of the old south gate. Below the choir was clearly the crypt for the castellans. The presbyterium was built on a rather older wall course. It may have appeared as part of the strengthening of the fortifications during the Hussite raids and projects towards the south. The tower-like attachment south of the choir has survived up to the second floor (rear part) and is divided by two ledges (Kaffgesimse). Small rectangular window openings once lit the interior of the ground floor room with its two groin vaults. An elevated door in the east wall leads to the projection (Vorsprung) of the old wall. In front of the tower, the outer walls of a staircase tower is visible; this was also accessible from the nave. Entry to the extension was through an inflexed arch in the wall of the choir. The choir is supported outside by once stepped buttresses with gothic arch windows between them. In the eastern window the original tracery has survived. Nave and choir are separated by a profiled choir arch. Decorative shields can still be made out on the rib intersections on the net vaulting above the choir. Only the base of the original wall survives on the north side of the nave, the remaining material was changed during an inappropriately executed renovation. Like the rest of the castle, the chapel walls were made out of the Rhaetian sandstone on which it was built. The regular ashlars were set in place with an external lewis (scissor tongs or Mauerzange) which left marks on the stone. The inventory mentions numerous fragments of gravestones in the chapel floor. Around 1980, some pieces could still be seen, which have since disappeared or become concealed. The gradual slippage of the castle rock caused the
