The Castillo de San Marcos opens its’ door to the community for Free during the Castillo Holiday Open House on December 8th from 6:00pm-8:00pm. This St. Augustine Holiday tradition allows visitors to informally explore the Castillo by lantern light, interacting with staff and volunteers dressed to represent the more than 300 years of Castillo history.

Cannon firings will take place at 6:00pm (this one kicks off the annual Boat Regata), 7:00pm, and 8:00pm.
