Located as natural seawall in the center of Masan Bay serving, Dot Island is a small but beautiful island measuring 112,000m² at an altitude of 52.8m. The island has a legend of the king of Garak Kingdom and a beautiful woman named Mihee. The island was called Dot Island, which is named after 'Dot,' the old term to refer to a pig as the island is in the shape of a pig. There is a possibility that the island is named Dot due to a local tale of heroic figure Choi Chi-won born as a son of a golden pig. Before opening as a maritime tourist attraction in 1982, few households resided in the island mainly being in the fishery industry. For local kids, Wolpo Branch Elementary School was opened.
After creating a maritime park through a private investment project, the island gained reputation as a tourist attraction. Thanks to the efforts to turn it into an eco-friendly maritime cultural space since 2011, 20 sculptures were installed with support from the 2012 Changwon Sculpture Biennale. To preserve the island's environment and maintain its unique attractiveness, the 2014 Changwon Sculpture Biennale decided not to install additional sculptures but carried out renewal activities to turn the existing facilities built as a tourist attraction into artworks.
