The Medieval Monuments in Kosovo are a World Heritage Site that includes four Serbian Orthodox Christian churches and monasteries. These buildings show a mix of eastern Orthodox Byzantine and western Romanesque styles, creating the Palaiologian Renaissance style. They were built by members of the Nemanjić family, the most important royal family in Serbia during the Middle Ages. These sites are located in Kosovo.

In 2004, UNESCO recognized the Dečani Monastery for its special value. Two years later, the site was expanded to include three other religious places: the Patriarchate of Peć Monastery, Our Lady of Ljeviš, and Gračanica Monastery.

In 2006, the site was added to the list of World Heritage in Danger because of problems with managing and protecting the monuments. These issues were caused by political instability in the region.

UNESCO controversy

There is an ongoing disagreement about Kosovo's attempt to join UNESCO, which would mean the cultural sites in Kosovo would be listed separately from Serbia. These historical monuments have faced damage, especially during ethnic violence in 2004, when Kosovo was under UNMIK management. During this time, the Our Lady of Ljeviš church was seriously harmed. In October 2015, the UNESCO Executive Board suggested Kosovo could become a member. The membership request was then discussed at the UNESCO General Conference in November 2015.

UNESCO did not accept Kosovo as a member because the proposal did not receive more than two-thirds of the votes at the General Conference in Paris on November 9, 2015. A major reason for the rejection was the 2004 unrest in Kosovo, during which 35 Orthodox churches were damaged or destroyed, including the Our Lady of Ljeviš, a World Heritage Site. The church continues to face theft, including the repeated stealing of valuable lead from its roof.
