The World Monuments Fund has described Tvrđa as "a unique example of an eighteenth-century baroque military, administrative, and commercial urban center". Tvrđa is on Croatia's 'Tentative List' for consideration as nominee for the World Heritage Site. During the 1991–95 conflict in Croatia, 90 per cent of the buildings in Tvrđa were damaged to some extent and the fort was featured on the 1996 World Monuments Watch List of Most Endangered Sites. It has not appeared on the list, published every two years, since.
