A 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.

Plan Your Visit

Unique among National Parks, the Castillo de San Marcos embodies nearly 450 years of history and culture that can not be fully experienced in a single visit. The Castillo de San Marcos National Monument is located in downtown St. Augustine, Florida. St. Augustine is located on Florida’s Northeastern Atlantic coast about midway between Jacksonville and Daytona Beach.

Getting Around

The Castillo, like most of downtown St. Augustine, is primarily a pedestrian area. Walking is the best way to visit the historic district which is about one mile long by 1/2 mile wide.
