Castillo San José

Castillo San José is a stone fortification perched on Cordillera Hill that overlooks Valparaíso Bay with expansive views across the water. The interior contains exhibition rooms with artifacts and documents related to Chile's naval past and the region's defense strategies.

The fortification was built in 1692 to defend against European privateers, but was nearly destroyed during the 1822 earthquake that devastated the region. The structure was later rebuilt and has remained a significant historical landmark since its reconstruction.

The fortress now serves as a center for maritime knowledge, displaying the strong connection between Valparaíso and the sea. The collections show how naval traditions shaped the city and its relationship with the coast.

The site is open daily except Mondays, and guided tours can be arranged in advance for better understanding of the exhibits. The hilltop location requires climbing some stairs, but the view across the bay rewards the effort.

A Scottish watchmaker named Juan Mouat established the first astronomical observatory on the Pacific Coast within the fortress grounds in 1843. This facility was groundbreaking for celestial observation in the southern hemisphere and attracted scholars from across the region.
