White Carniola
During the 18th century, the castle was damaged by fire twice (in 1705 and 1790); after repairs it was bought by Jožef Savinšek in 1792. It survived World War II intact and was afterward nationalized without compensation and converted into the headquarters of the Museum of White Carniola (), established in 1951, and became home to some of its permanent collections. Exhibits include a cultural history of White Carniola, collections of Roman and medieval stone markers and memorials, and an ethnological collection on the historical way of life in White Carniola. The former castle stables and other outbuildings house the Metlika Slovene Firefighting Museum. In addition, the second floor contains a wedding hall, and the basement a wine cellar. Metlika Castle also features the Gangl Gallery for temporary exhibitions, which is part of Museum of White Carniola.
