La Fortaleza, also known as Palacio de Santa Catalina, is the official residence and workplace of the Governor of Puerto Rico. Located in Old San Juan, it is the oldest executive mansion in continuous use in the Americas, having served as the governor’s residence since 1544. Built between 1533 and 1540, La Fortaleza was the first fortification constructed by the Spanish on San Juan Islet to defend San Juan Bay. It has also served as a fortress, an arsenal, and a prison throughout its history. In 1983, La Fortaleza was designated a UNESCO World Heritage Site as part of the San Juan National Historic Site.

La Fortaleza features a blend of Spanish Renaissance and Neoclassical architectural styles. The complex includes two towers: the Homage Tower and the Austral Tower. The Homage Tower houses the Santa Catalina Chapel, known for its colorful mosaic of 95,000 pieces in honor of the Holy Trinity. The interior also contains lush gardens and a swimming pool.
