I. PROJECT BACKGROUND

The objects that are to be treated through this project are located throughout the San Juan National Historic Site. The various commemorative plaques memorialize different historic events and important designations associated with the historic site. The rails and pins are important structural remnants of the artillery emplacements that once were common throughout the park but that, because of the harsh environmental conditions (salt air, high humidity, abrupt changes in temperature), wear and human action have made them almost disappear. The features that will be conserved through this project are the last of their kind in the fortifications.
