The monastery with a church dedicated to St. Nicholas was built during the peak of the Rudnik region's prosperity, around 1425. Its founder was the nobleman Nikola Dojranović, as indicated by the inscription above the entrance portal. The monastery church is a single-nave structure with a rectangular base, vaulted with a barrel vault, and features a slender octagonal dome above the central space of the nave. It was constructed from roughly hewn stone and yellowish tufa, with facades originally grouted with red mortar. During its restoration in the early 19th century, the church was plastered and whitewashed. At that time, geometric ornaments were added to the drum of the dome and around the windows. The gable roof was once covered with wooden shingles but is now clad in copper sheets. The mentioned monumental western portal was crafted from white profiled marble and bears the founder's inscription. To the west is a large, square-shaped narthex vaulted with a cylindrical vault, and west of it, in 1817, a two-story bell tower was added, built in the style of medieval towers. The bell tower has a square base and a flat wooden interstory structure. The western entrance features a triple-profiled frame. Above it there are three lunettes that originally contained depictions of the church's patron saints, though these frescoes have been destroyed over time. Above the ground floor of the bell tower, each floor has arched windows, and the structure is topped with a steep hipped roof covered in metal sheets.

Inside the church, three layers of frescoes are partially preserved: the original layer in the altar zone, dating back to 1425; frescoes in the narthex from the early 17th century; and those in the upper zones of the nave from 1850.
