These antiquities embrace at the present time, the “Spanish Mission,” the “Old Fort” and the “Rock House,” the latter within the last few years having been destroyed by the removal of the shell mound on which it was built, for road making purposes. This building as well as that of the Spanish Mission, however, has been perpetuated by photographs of which the Florida State Historical Society has authenticated copies.
