Church of the Holy First Martyr Stephen (Serbian: Црква Светог Првомученика Стефана/Crkva Svetog Prvomučenika Stefana), better known as the Lazarica Church (Serbian: Црква Лазарица/Crkva Lazarica), is a Serbian Orthodox church in Kruševac, Serbia. It was built in 1375-1378 as an endowment of prince Lazar of Serbia. Lazarica, as an outstanding achievement of the Serbian medieval architecture, was declared a Monument of Culture of Exceptional Importance in 1979, and it is protected by the Republic of Serbia. Lazarica was built as a prototype of the Morava school of architecture, as a palace church associated with the Kruševac Fortress, the capital of Prince Lazar. Today, only Lazarica and parts of the keep remain from the vast fortress complex.
