Introduction

Castillo de San Marcos in St. Augustine, Florida, is the oldest masonry fort in the continental United States, built by Spanish colonial authorities between 1672 and 1695 to defend the important port of St. Augustine. The fort is constructed of coquina, a local limestone of compressed ancient shells that absorbs cannon fire without shattering, helping the fort withstand repeated British attacks. Its star-shaped bastion design exemplifies European military engineering in North American colonies. The fort passed through Spanish, British, and American rule and was designated a US National Monument in 1924, standing as St. Augustine's most important historic landmark.
