The rectangular sacristy, which is accessed from the northern narrow corridor, is abutted by a rectangular courtyard.
It is cruciform, with four-bay elevations to the nave, a single-bay chancel, a single-bay sacristy and two-bay transepts.
The sacristy on the south wall and the statuary on the west frontage probably concealed the remaining four crosses.
The chapel was built in the old sacristy of the church and in 1433 it was decided to place there an altarpiece.
The rococo sacristy is elaborately painted, stuccoed, and decorated with polychrome marble.
Among the people buried was an embalmed 19th century priest and in the sacristy a young woman was found.
The parish's assembly room, sitting room, offices, and sacristy are located towards the southeast/southwest.
It was built with a single apse, now replaced by a sacristy.
