Rectangular-plan chapel, situated on a north-south axis. The building is built of red local sandstone, on a high plinth. The front originally features a Doric four-column portico. The central part of the façade is risalitic. In it, a rectangular doorway framed by moulded white sandstone. Above it is a semi-circular skylight. Originally all walls were surrounded by a cornice. The corners of the building may have originally been accentuated with pilasters. The side walls are pierced by two circular and one rectangular window with a complete arch. The rear elevation is chisalitised, with a doorway on the axis leading to the sacristy. Above it is a semicircular skylight. A few fragments of plaster originally covering the entire chapel are preserved inside and out. Outside, marked rustication in the plaster. The roof was originally gabled.

Interior divided into two unequal parts The first part is larger, closed from the north by an altar wall. In it, symmetrical remains of doorways leading to the sacristy, from which there was an exit to the outside. Next to the sacristy there are two small annexes, from which it was probably possible to access the attic. At the entrance to the chapel there is a visible exit to the crypt, where there are the remains of coffins, including a child's coffin.
