The first archaeological interventions of Plaoshnik occurred in the period from October 1942, until May 1943 (with interruptions), on the interior of the remains of the Sultan Mehmed Mosque organized by the Office of Antiquities in Ohrid, headed by its head Kiril Prlicev, and then with Dimce Koco. The remains of the old St. Clement's church and the grave of St. Clement of Ohrid were also found.
The total results of these archaeological excavations were published by Professor Dimce Koco in 1948. In the period from 1960-1964-1966, archaeological excavations of Imaret (Plaoshnik) are being performed again, revealing in parallel the early Christian policonchal church from the 5th -6th century. In the months August-September 1965 the Republic Institute for the Protection of Cultural Monuments-Skopje carried out archaeological-conservation research in the area of St. Clement's church "St. Panteleimon", after which conservation works were performed.
