“Royal Bistrica” is a former palace of the rulers of the Third Bulgarian Kingdom. Located above the resort of Borovets in Rila. It was built between 1898 and 1914 and was performing the functions of a hunting lodge for the kings Ferdinand I and Boris III. Architectural appearance is influenced by the traditional Bulgarian style but together with this it could be seen also European architectural influences.
