century The first archaeological excavations of the site were carried out in 1927 by Dr Radoslav Grujić, with help of the Ministry of Religion and the army and navy. During that research, several objects were detected in the area of the Bistrica: The main church dedicated to the Holy Archangels A small church dedicated to St. Nicholas Part of the dormitory and other buildings along the rampart near the Bistrica In the area of Višegrad, only a small research was conducted, in which the church dedicated to St. Nicholas and several other buildings were found. Inside the main church they found the remains of the imperial tomb, in which were supposedly the bones of Emperor Dušan. Two years later Dušan's remains were transferred to Belgrade and buried in a separate coffin in the St. Mark's Church, up until the full restoration of the monastery. The found parts of the famous mosaic flooring, decorative plastic and paintings were transferred to the Museum of Southern Serbia (now Museum of Macedonia) in Skopje, where they are still located, but it is not known where the other artifacts which are mentioned in Grujić's reports are, thus they are today considered permanently lost, In addition, parts of mosaic floor were further damaged during the transport to Skopje. Shortly before the 1926 excavations, the first Hydroelectric power plant in Kosovo and Metohija, Prizrenka, was built next to the monastery complex, completed in 1928, which was active until the 1960s, while today it is under state protection as a monument. After World War II, research on the complex was continued from 1961 to 1965, with parallel conservation work undergone. The research team was headed by Dr Slobodan Nenadović. During this period he researched the eastern and northeastern part of the plateau near the Bistrica river, which revealed most of the dormitory, and the dining room. Upon completion of works, a marble slab was placed on the site of Dušan's tomb. The head of the subsequent research team, Mihailo Milinković, presented serious objections to the methods of research in this period, which in his opinion, were only of the architectural character and were not in accordance with the principles of archaeological practice. In addition, he pointed out that the material were not singled out and preserved, but with the rest of the material thrown into the Bistrica.
