St. Augustine’s Castillo de San Marco

A St Augustine monument not only of stone and mortar but of human determination and endurance, the Castillo de San Marcos symbolizes the clash between cultures which ultimately resulted in our uniquely unified nation. Still resonant with the struggles of an earlier time, these original walls provide tangible evidence of America’s grim but remarkable history.

Though its construction started in 1672 the Castillo de San Marcos’ history embodies the struggle and contest of the entire colonial era as well as the foundations of American identity.

Architecture & Construction

The Monument site consists of 20.5 acres and includes a reconstructed section of the walled defense line surrounding the city of St. Augustine incorporating the original city gates. The Castillo de San Marcos’ architecture and detail are distinctive and unique. It is the oldest masonry and only extant 17th century fort in North America. As such it is an excellent example of the “bastion system” of fortification.

Arms & Armament

The 16th century colonization of American paralleled the development of new weaponry. This technology centered on black powder (gunpowder) based systems. The cannon, first made of iron, later of bronze, became the weapon of political power projection and along with small arms of various types began to dominate the battlefields of both Europe and the New World.

How We Tell Our Story…

… we re-live it. The Castillo comes alive through a diverse range of programs which include Ranger talks, museum exhibits, historical weapons demonstrations, living history reenactments, and special events. Don’t miss your best chance to see history in action. No time machine necessary.
