Foundation and First Mentions
The city of Castro was officially founded on 12 February 1567 by the Spanish conquistador and marshal Martín Ruiz de Gamboa. The settlement was originally named Santiago de Castro in honour of the then Viceroy of Peru, Lope García de Castro.
This historical event makes Castro the third oldest continuously existing city in the territory of modern Chile (after Santiago and La Serena). From the moment of its foundation, it became the main stronghold of Spanish colonisation on the Chiloé Archipelago.
Key Development Factors
The transformation of a small settlement into an important urban centre was driven by a number of strategic reasons:
- Geographic Protection: The city was established on the shores of a narrow fjord on the eastern coast of Isla Grande. This location provided natural protection from Pacific storms and created a convenient harbour for ships.
- Political Role: Castro was initially conceived as an administrative centre from which the entire archipelago was managed and the indigenous population (the Huilliche people) was controlled.
- Resource Base: The surrounding forests provided abundant material for shipbuilding and repairs, which was critical for the maritime logistics of that era.
Early Cultural and Economic Features
In the first centuries of its existence, Castro's economy was based on agriculture (growing potatoes and grains) and timber harvesting. A crucial cultural factor was the arrival of the Jesuits in the 17th century, who made the city the centre of their missionary activity. It was here that the unique traditions of wooden architecture and a syncretic culture, combining Spanish and local customs, began to form.
The city's early history was also marked by a struggle for survival: distance from the metropolis and repeated attacks by Dutch corsairs (specifically the expeditions of Baltazar de Cordes and Hendrick Brouwer) in the 17th century caused serious damage, forcing residents to constantly rebuild the city.
