Old Fort Park

Mysterious 40-by-80-foot coquina ruins, reminiscent of St. Augustine's Castillo de San Marcos, that overlook the Intracoastal Waterway near New Smyrna's downtown. At first glance, the ruins appear to be those of a Spanish fort, but credit for the structure is generally given to the Scottish physician who founded the town, Dr. Andrew Turnbull. The appearance and location of the structure have led to much speculation about its origin and purpose. Unfortunately, it's unlikely anyone will ever know for certain whether the structure was a colonial church, Dr. Turnbull's mansion, a site for constructing ships or the original Castillo de San Marcos.
