Baluarte de San Diego

Baluarte de San Diego is a fortification with a distinctive ace-of-spades shape positioned at the southwestern corner of Intramuros. The structure comprises thick stone walls arranged across multiple levels, creating various defensive positions and interior chambers.

The structure was built between 1586 and 1587 under the direction of Jesuit priest Antonio Sedeño. It replaced an earlier fort and was later reconstructed after British forces damaged it in 1762, when it received its current name.

The name references Saint James, Spain's patron saint, reflecting the religious purpose woven into colonial military design. Inside, visitors notice how the spaces once served both ceremonial and administrative functions for Spanish governors.

Visitors can reach all levels of the fortification through stone pathways, though sturdy footwear is recommended for the uneven surfaces. The surrounding garden area provides spaces to rest and take photographs.

Archaeological excavations in the 1970s revealed multiple concentric layers within the bastion, showing how the structure was expanded and modified over time. These layers provide insight into how defensive techniques evolved during the colonial period.
