Demolitions associated with the war, as well as reconstruction, destroyed several institutions and cultural or religious symbols including the Gazi Husrev-beg Library, the national library, the Sarajevo Oriental Institute, and a museum dedicated to the 1984 Winter Olympics. Consequently, the different levels of government established strong cultural protection laws and institutions. Bodies charged with cultural preservation in Sarajevo include the Institute for the Protection of the Cultural, Historical and Natural Heritage of Bosnia and Herzegovina (and their Sarajevo Canton counterpart), and the Bosnia and Herzegovina Commission to Preserve National Monuments.
