indrical windows were placed in the eastern facade of the chancel and in the northern transept. In the gable wall of the chancel, the rosette was placed above the triad of windows with profiled frames with pellet decoration embedded in the archivolt. The side elevations of the church were divided by flat buttresses or pilaster strips, between which semicircular, small windows were pierced.
The interior of the church is characterized by clear divisions and consistent composition. Inter-nave arcades with squat pillars and semicircular arches support the high walls, the upper part of which is separated by a cornice and contains windows. Above the cornice, on the capitals of semi-columns are massive arch bands, and prominent ribs are mounted on corbels added on the sides of the lesenes. The inter-nave pillars were equipped with semi-columns on which the internal stepped arcades are separated, receiving one of the classical motifs of western romanism. The naves of the church is covered with rib vaults separated by massive arch bands.
Access to the attic of the aisles was provided by semi-circular vaulted narrow passages at the height of the organ gallery. In the eastern part of the church, in the chapels and the northern transept, semicircular niches of piscinas for washing liturgical vessels with preserved chute channels and cupboards were placed. In the southern wall of the nave, within the cloister running there, there was a semicircular niche with a seat, a place where the abbot sat at certain hours, giving advices to monks.
The monastery buildings were adjoined to the church from the south, but in the first half of the 13th century only the eastern wing, adjacent to the transept, was built. It was erected of bricks with the use of sandstone to make structural elements and architectural details. The eastern wing reached 35 meters long and 12 meters wide. From the north, in the ground floor, there was a sacristy, chapter house, stairs to the dormitory located at the upper floor, under which there was a prison (accessible from the adjacent room), then a warming room, a day room and adjacent latrines.
The chapter house, which was the place for the convent’s daily meetings, measuring 9.7 x 9 meters, was covered with a vault based on a central, squat column with a carved capital entwined with plant springs. On this head and on wall corbels rested arch bands separating the bays of the vaults and ribs, reinforced at the intersection with bosses. One of them received a form of convex relief with four heads in contact with chins. The other three bosses are decorated with floral motifs. A similar decoration as the capital of the central column had columns and half-columns placed in the open-works (two-light openings) from the cloister side. In the Middle Ages, rows of stone benches stretched against the walls of the chapter house, while in the middle there was probably a lector’s desk. The support of the vault on one pillar at the square bays made it necessary to place the corbel on the entrance axis, which was solved by building a pillar dividing the cloister portal, where lay brothers and novices gathered during the meetings, watching the interior of the chapter house through the open-works.
The day room had a similar form and dimensions to the chapter house with a central column supporting the vault. It was a room used for brothers to perform manual work, especially in the winter. Together with the neighboring warming room, it was the only room heated in winter. On both sides of the wall separating them were heating installations, two hypocaustum furnaces with a common vent. Each of the furnaces consisted of a hearth and a grate chamber, with the hearth covered by a grate supported by brick arcades. The hearth walls were also made of bricks and the bottom was lined with large stones. The walls of the day room received very deep foundations (over 4 meters), as well as a seven-meter annex with latrines, reaching slightly beyond the riverside slope, to the drainage channel towards Pilica.
