The Church of the Exaltation of the Holy Cross of Apollona was built on the site of an earlier church dedicated to the Virgin Mary. The church was completed on May 2 1858, as stated in the founding inscription of the western entrance. It is a single-naved basilica with a cross-dome, a narthex and a women's chapel, a five-story bell tower and a pebbled floor dating from 1870. It has a richly decorated wood-carved iconostasis, erected in the Ottoman Baroque style. Its despotic icons date back to 1863, with the exception of the icon of Christ, the metal sheet cover of which dates back to 1772.

The exhibition space consists of buildings that were built at different times. The oldest was built in 1945, and it was called the "cells", that is, the auxiliary spaces next to the church. From 1946 to 1948 it functioned as a school. The two-story part of the building during the 1950s served as a medical office on the ground floor and a doctor's residence on the first floor. Of the remaining cells, one was the parish office, another the living space of the candlemaker, and the other two were storage spaces. The newer part of the building has been built recently and is located to the east of the cells.
