Lastovo is an island municipality in the Dubrovnik-Neretva County in Croatia. The municipality consists of 46 islands with a total population of 792 people, of which 93% are ethnic Croats, and a land area of approximately 53 square kilometres (20 sq mi). The biggest island in the municipality is also named Lastovo, as is the largest town. The majority of the population lives on the 46 square kilometres (18 sq mi) island of Lastovo. The island is noted for its 15th- and 16th-century Venetian architecture. There is a large number of churches of relatively small size, a testament to the island's long-standing Roman Catholic tradition. The major cultural event is the Poklade, or carnival. The island largely relies on its natural environment to attract tourists each season. In 2006 the Croatian Government made the island and its archipelago a nature park
