San Juan National Historic Site
History and museums
San Juan National Historic Site in the Old San Juan section of San Juan, Puerto Rico, is a National Park Service-managed historic site which protects and interprets colonial-era forts such as Castillo San Felipe del Morro, bastions, powder houses, and three fourths of the old city wall.
By a February 14, 1949 decree the site was established, and noted the need to protect the fortifications as monuments as well as preserve their historical and architectural value. Listed on the National Register of Historic Places on October 15, 1966.
On December 6, 1983, the park and La Fortaleza were together designated a World Heritage Site under the name "La Fortaleza and San Juan National Historic Site in Puerto Rico". Only 12 national park areas in the United States are considered World Heritage Sites.
