Castro is the main urban center of Chiloé Island, located in southern Chile's Los Lagos Region. It serves as the capital of Chiloé Province and functions as a commercial and cultural hub for the archipelago. According to the 2002 census the city had 39,366 inhabitants; more recent counts record population growth typical of regional centers, though figures vary by source.

Geography and urban layout

The city sits on gently rolling terrain beside a sheltered bay and is linked by roads and ferries to other islands and the mainland. Castro's waterfront and neighborhoods blend maritime activity with residential districts. One of its most distinctive sights are the palafitos: colorful wooden houses built on stilts along the tidal shoreline, which speak to the community's adaptation to coastal conditions.

History and heritage

Castro traces its origins to the Spanish colonial era and was established as an organized settlement in the 16th century. Over centuries it developed a regional architectural tradition that blends local timber craftsmanship with Catholic mission influences. Several Chiloé wooden churches, including the Church of San Francisco in Castro, are recognized as part of the Churches of Chiloé World Heritage ensemble inscribed by UNESCO for their unique building techniques and cultural value.

Economy, culture and uses

The city's economy is based on fishing, aquaculture (notably salmon farming in the region), agriculture, public services and a growing tourism sector. Local culture emphasizes maritime livelihoods, traditional cuisine such as curanto, and communal practices like the minga (a cooperative moving or building effort). Craftsmanship in woodwork and boatbuilding remains important to both daily life and the tourist economy.
