The eastern shore of Guanica Bay is where US Marines and Army troops landed on 25 July 1898, opening the Puerto Rico campaign of the Spanish-American War. A modest monument by the malecón marks the spot, along with interpretive signs in Spanish and English describing the landing and the brief skirmish that followed.
The site is a few minutes' walk from the centre of town and pairs well with a stroll along the waterfront. For a deeper look, the Yauco Battle Site northeast of town preserves the location of one of the larger engagements that followed the landing.
