In 2004, UNESCO recognised the Visoki Dečani monastery as World Heritage Site for its outstanding universal value. Two years later, the site of patrimony was extended as a serial nomination, to include three other religious monuments: Patriarchate of Peja, Our Lady of Ljeviš and Gračanica monastery under the name of Medieval Monuments in Kosovo. It consists of four Serbian Orthodox churches and monasteries, which represent the fusion of the eastern Orthodox Byzantine and the western Romanesque ecclesiastical architecture to form the Palaiologian Renaissance style. The construction was founded by members of Nemanjić dynasty, the most important dynasty of Serbia in the Middle Ages.
