Capitol of Puerto Rico

El Monumento de la Recordación (English: Monument of Remembrance) is a memorial monument and monolith erected in San Juan, Puerto Rico that honors Puerto Ricans who have fallen in combat in service of the United States Armed Forces. The monument was unveiled on May 19, 1996 as a granite wall engraved with the names of Puerto Rican soldiers who died during combat. As of 2009, the monument was etched with the names of more than 2,000 service members.The monument largely contains the names of soldiers who had a Puerto Rico address at their time of enlistment and/or death. If a soldier had a stateside address their name is most likely not on the monument. Because so many Puerto Ricans in the military list a United States address, their participation is underrepresented in statistics.A sculpture by Victor Gutierrez called Llama de la eternidad (Flame of eternity) is located in the center of monument.A service is held each year on Memorial Day at the Monumento de la Recordación. In 2019, attendees learned that two fallen soldiers from Puerto Rico had been recently identified as part of the Recovery of US human remains from the Korean War.

The San Juan City Wall (Spanish: Murallas del Viejo San Juan) is a city wall that surrounds the western end of the Islet of San Juan, site of the historic Old San Juan district in San Juan, Puerto Rico. This defensive wall system was built between the 16th and 20th centuries to protect the city and the Bay of San Juan, a highly strategic point in the Caribbean. These walls, along with the defensive fortresses in Old San Juan (La Fortaleza, El Morro and San Cristóbal), form part of the UNESCO World Heritage Site-designated San Juan National Historic Site as they are characteristic examples of the historic methods of construction used in military architecture which adapted European designs and techniques to the special conditions of the Caribbean port cities.San Juan remains the only walled city under the United States jurisdiction, with walled cities like Boston, Charleston and New Orleans no longer having walls after the 18th century, although St. Augustine, Florida still retains several wall remnants. Examples of other North American walled cities that retain their ramparts are Quebec City in Canada and Campeche in Mexico. The bartizans (garitas) found along the walls are considered emblematic of the city of San Juan and a symbol of historic heritage preservation in Puerto Rico.
