The Orthodox Cathedral of the Holy Trinity in Gjakova was destroyed by the communists in 1949. Prior to 1968, the Yugoslav state carried out the destruction of churches, the listing of church properties as state cultural heritage, the seizure of church and monastery artifacts to be displayed in state museums, as well as, the appropriation of property for state functions. During 1968 and 1981 protests, Serbian Orthodox religious sites were the target of vandalism, while vandalism continued during the 1980s. There were attempts to devastate Devič, damage Visoki Dečani and desecrate Gračanica and the Hermitage of St. Peter of Koriša. In March 1981, the Patriarchal Monastery of Peć was set on fire, which destroyed a 2,000-square meter residential section along with valuable furniture, rare liturgical books and some of the monastery's treasury.
