Castillo de San Marcos
St. Augustine, Florida, USA
The Castillo de San Marcos is the oldest masonry
fort in the continental United States. Located on the shore of Matanzas
Bay, construction began in 1672, 107 years after the city's founding
by Spanish Admiral and conquistador Pedro Menéndez de Avilés,
when Florida was part of the Spanish Empire.
After Britain gained control of Florida in 1763,
St. Augustine became the capital of British East Florida, and the
fort was renamed Fort St. Mark until the Peace of Paris (1783) when
Florida was transferred back to Spain. In 1819 Spain signed the
AdamsOnís Treaty which ceded Florida to the United
States in 1821 and the fort became a United States Army base which
was renamed Fort Marion. In 1942 the original name, Castillo de
San Marcos, was restored by an Act of Congress. The fort was declared
a National Monument in 1924 and after 251 years of continuous military
possession, the fort was deactivated in 1933 and the site was turned
over to the United States National Park Service.
