The Royal Palace of Cetinje houses the history collection of the National Museum of Montenegro. The building is a neoclassical structure from 1867, modest in scale and simple in decoration — exactly the right size for a mountain principality that ruled a territory smaller than some European counties.
The interior has been preserved with period furnishings, photographs, weapons, and diplomatic gifts that collectively tell the story of the Petrović-Njegoš dynasty and the 35-year reign of King Nikola I (1860–1918). The throne room, the library, and the private apartments are all accessible. The palace faces the monastery across a small park, which was historically the main public space of the capital.
