Consisting mainly of forests and parks, Seurasaari is both an island and district of Helsinki. With no permanent residents, the island is home to the Seurasaari Open-Air Museum. The museum features a large collection of historical wooden buildings from across Finland. Aside from being an open-air museum, the island also serves as a popular outdoor reaction area with an abundance of hills, rocks, herb-rich forests, and wetlands. Several animals call the island home. In 1890, it was officially named a public park. Two years later, a bridge to the island from Helsinki was built so that visitors wouldn't have to travel boat to the park. Each year more than 100,000 visitors take to the island to enjoy its numerous amenities. The island is also home to a mid-summer celebration that draws large crowds. Part of the festival includes a giant bonfire built on a small isle just off the island's coast. Newlyweds light the fire that is then viewed by island visitors. Seurasaari is home to a unique nudist beach that unlike most nudist beaches, hosts segregated areas for men and women. The beach is one of only two nudist beaches in Helsinki and one of only three in all of Finland.
