Fortín de San Gerónimo

San Gerónimo

The San Gerónimo and San Antonio forts were pivotal in repelling the invasion by the forces of British Admiral Henry Harvey and Sir Ralph Abercromby in 1797. On April 17, 1797, their combined forces (64 to 68 ships and 7,000 to 13,000 men) landed in Cangrejos, approximately three miles west of San Juan. San Juan's military forces, which included, among others, the Regimiento Fijo de Puerto Rico (Resident Regiment of Puerto Rico) and the Militias Disciplinadas (Trained Militias) were outnumbered by the invaders by a ratio of almost three to one. Admiral Harvey blockaded the San Juan Harbor while Abercromby established his operations headquarters in San Mateo parish overseeing all of San Juan and the Martín Peña Bridge. Abercromby's strategy was to take the Martín Peña bridge in order to block Spanish reinforcements from the south and bombard San Gerónimo and San Antonio from Miramar to gain access to and cross the San Antonio Bridge into the San Juan islet. British forces included the Royal Marines, made famous by their later defeat of Napoleon's troops in Egypt. Then-Governor of Puerto Rico Field Marshal Don Ramón de Castro y Gutiérrez, a brilliant strategist, prevented the British from advancing and frustrated their conquest of San Juan.

The San Gerónimo and San Antonio sustained heavy damage from the constant bombardment during the two-week siege on the city. Chronicles describe the defenders shooting their muskets and cannons from behind sandbags because of the devastation their forts sustained. Both San Gerónimo and San Antonio were eventually rebuilt and expanded.

San Gerónimo is located adjacent to the grounds of the Caribe Hilton Hotel. It was listed on the National Register of Historic Places on October 11, 1983. Unlike similar forts near Old San Juan, it is not part of San Juan National Historic Site. San Gerónimo is owned by the Institute of Puerto Rican Culture but is managed by the Hilton. Thanks to the work of volunteers, the fort is again open to the public and contains an exhibit of the history of San Juan. The "Polvorín de San Gerónimo", or gunpowder house, that was built in 1769 and supplied the fort with gunpowder, is now part of the Luis Muñoz Rivera Park nearby.

As recent as the year 2006, attempts were being made by the Instituto de Cultura Puertorriqueña and the U.S. Army Corps of Engineers to build a breakwater to stop any further deterioration from irreparably damaging the centuries-old fort. Senate Vice President Orlando Parga has led efforts to modify some of the construction projects that would encroach on the fort or would hamper the Corps of Engineers' preservation and reconstruction efforts.

In July 2007, the Fort was the scene of protests against the construction of a tourist project called Paseo Caribe that would block access to the fortification. Protesters argued that the public should have free access to it. The protest lasted about a week during which the protesters halted the construction projects by climbing onto the cranes.

The Omnibus Public Land Management Act of 2009 directed the U.S. Secretary of the Interior to conduct a study to determine the suitability of including San Gerónimo as part of San Juan National Historic Site.[3]

After two decades closed to the public, in 2018 the "Asociación Amigos del Fortín de San Jerónimo" was created, a non-profit association that is responsible for the preservation and future reopening for the charity of the Puerto Rican people and tourists.
