Aleutian World War II National Historic Area
National Park Service
Unalaska/Dutch Harbor, Alaska

The Aleutian World War II National Historic Area at Ulakta Head on Amaknak Island encompasses the historic footprint of the U.S. Army base, Fort Schwatka. Located in the Alaskan Aleutian Island Chain, the fort was one of four coastal defense posts built to protect the harbors and waters of Unalaska during World War II. Construction began in September 1942, and by 1943 most of the installations were operational. In 1996, Congress designated this a National Historic Area.

ARG conducted a conditions assessment and materials investigations of five of the remaining concrete structures to evaluate the nature and extent of the material deterioration evident in the structures and to determine the deterioration causes. Several treatments were developed to stabilize the structures and treat the conditions of material deterioration in the severe environmental conditions. ARG also undertook an analysis of architectural issues relating to accessibility, rehabilitation, and interpretation of the site.
