Biljarda
Biljarda (Serbian and Montenegrin Cyrillic: Биљарда) is a (former) royal residence in Cetinje, the historic capital of Montenegro. The palace is located in the historic center of Cetinje, near the Cetinje Monastery. Prince-Bishop Petar II Petrović-Njegoš started the building of the palace on 29 March 1838. Initially, it was called the 'New House', but soon it got its new name 'Biljarda' (Billiard House) after the central room on the first floor which contained a billiard table, the prince-bishop's favorite game. Designed by the Russian Lieutenant Colonel Jakov Nikolaevich Ozeretskovsky, the Biljarda palace has the appearance  of a medieval fortified feudal castle: a rectangular two-storied stone building, covered with lead, enclosed by a high stone wall with four defensive towers on the corners. At the time of its construction, it was an impressive building, over 70 metres in length and 7.5 metres wide. It contains eleven rooms on the ground floor and 14 rooms on the first floor. The palace was not only the home of the prince-bishop, but also provided accommodation to the Senate and other state authorities as well as being a guest house for important visitors. The palace served as a  royal residence until 1867, when the Montenegrin royal family moved to King Nikola's Palace. At the start of the 20th century, it housed various ministries and the two world wars it was used by the military. Currently, it is part of the National Museum of Montenegro.
