Metelkova (full name in Slovene: Avtonomni kulturni center Metelkova mesto, "Metelkova City Autonomous Cultural Centre", referred to by the acronym AKC) is an autonomous social and cultural centre in the city centre of Ljubljana, Slovenia's capital city. Formerly, the site was the military headquarters of the Army of the Austro-Hungarian Empire, then it became the Slovenian headquarters of the Yugoslav People's Army. It consists of seven buildings (military barracks) extended over a total area of 12,500 m2, which have been squatted since September 1993. The squat is named after nearby Metelko Street (Slovene: Metelkova ulica), which is named after the 19th-century Slovenian Roman Catholic priest, philologist, and unsuccessful language reformer Fran Metelko.
