America Begins Here

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.
