The nave opens to the aisles through nine arcades in each side, three of them "railed off" to prevent the entry of laymen. The main surface of the nave houses the baptismal font, the altar of Saint John the Baptist and Saint John the Evangelist, the altar of the Holy Saviour at the Cross and the ambo. The transept is separated from the nave by further screens and railings, in its southern arm is the altar of Saint Andrew and in its northern arm the altar of Saints Philipp and James. From the transcript the monks and lay brothers access the crypt. Finally, at the easternmost of the church is the presbytery with the high altar dedicated to Saint Mary and Saint Gall.
