The Caribbean islands offer the opportunity to experience the US Virgin Island and Puerto Rico National Parks. From historic forts to underwater snorkeling trails these parks offer a diverse array of things to see and do.
Puerto Rico National Park
San Juan National Historic Site
San Juan NHS is located within Old San Juan on the island of Puerto Rico. The park is open year-round and offers the opportunity to explore a historic fortification.
Juan Ponce de Leon founded Puerto Rico in 1509 on the northern coast of the island. San Juan was an important port for the Spanish with the port handling ships transporting silver, gold and other riches from the New World back to Europe.
Castillo San Felipe del Morro was constructed starting in 1539 by Spanish authorities. The construction of El Morro continued for two centuries. In 1595, English privateer Sir Francis Drake attacked El Morro at the request of Queen Elizabeth. He was driven back by the weaponry and soldiers at El Morro.
In 1598, after a 13-day siege English privateer, Sir George Clifford successively captured El Morro. He later abandoned the city because of disease and food shortage.
During the 1898 Spanish-American War the US warships fired on El Morro. This conflict resulted in the United States taking possession of Puerto Rico. Many generations of soldiers lived and worked within the forts.
The National Historic Site preserves the forts located in old San Juan.
Visitors today can explore Castillos san Cristóbal, San Felipe del Morro, and El Canuelo plus bastions, powder houses and ¾ of the wall erected around the old city. The views from the sentry tour are truly amazing.
San Juan National Historic Site was declared a UNESCO World Heritage Site in 1893.
