Baluarte de San Diego, Manila

Baluarte de San Diego is a bastion that was built on the southwestern corner of Intramuros, the walled city of the Philippines. The structure dates to the 16th century.

The bastion was meant to be part of a much larger fort, which was not completed. The bastion itself includes an outward projecting face and flanks that would have connected the bastion's face to the curtain wall.

Though it was built in 1587, the structure was altered many times over the years. These changes were documented in writings by Antonio de Morga. They were also evidenced by the archaeological excavation that uncovered the Baluarte de San Diego. That excavation began in 1979 and was completed in 1982.

The small park containing the Baluarte de San Diego includes gardens, landmarks, monuments and fountains.
