The Church of the Nativity of Christ with a refectory is an example of a representative temple from the eclecticism era, decorated in the baroque style, echoing the decor of the neighboring archbishop's residence. The first floor preserves elements from the 17th century, including the old gate church. The two-story building has an elongated shape, facing the street with its northern facade, surrounded by the monastery walls on the east and west. The composition consists of three rectangular volumes arranged one behind the other at slight angles. The central part is higher and covered with a gable roof, while the lower side parts, which are of equal length, have hipped roofs. The street facade of the central part is completed with three pediments: triangular on the sides and a lobed one in the center. Behind the pediments, the square base of the drum is preserved. To the east, lowered gates adjoin the building. The street and courtyard facades are similar in structure and decor. The middle part of the facade is highlighted with seven axes, flanked by two axes and a center of three axes. The side parts of the building are divided into two and three bays. On the first floor, these divisions are marked by short pilasters with square widths, while on the second, by panelled pilasters. The floors are separated by a cornice with a fillet that continues on the cornice of the monastery walls. The raised part is completed with an elaborate entablature with a cornice decorated with dentils. In the field of the middle pediment, there is a round window in a profiled frame. The first-floor windows are small, with architraves and framed casings, while the second-floor windows of the side parts are arched, partially false, with simple frames. The baroque casings of the high arched windows on the second floor of the central part with high sandriks look impressive. A cornice with dry biscuits runs along the top of the side volumes. The portals of the gate arches and entrances, the perspective framing of the openings, the pilasters with chamfers, and the wedge-shaped archivolts with round niches in the tympana are of interest. In the eastern part, the layout of the ancient two-span gates is preserved on the first floor. The former passage is covered with barrel vaults on supporting arches. In the raised volume, a large room in the eastern end and a room at the southern facade are covered with vaults on beams, while the other rooms have flat ceilings. The passage in the middle part of the first floor of the western volume has a ceiling of vaults on beams, as does the elongated room to its left. On the second floor, the eastern volume is divided into four rooms with dome vaults. The central volume houses a large hall of the church with a mirror vault, where large pilasters and window archivolts are preserved on the walls, transitioning into an arcade and onto the end walls, as well as round niches. In the western part, a staircase leads to two elongated rooms that precede the church.
