This is an attempt to document the forts and concrete emplacements built by the U.S. Army Corps of Engineers for the seacoast defenses of the "Modern era" (1890-1950). It includes four major generations of American coast defense construction (the Early Modern Programs (the "Endicott Board" and the "Taft Board"), the post-World War I batteries, and the WW II Modernization Programs), as well as those batteries built during emergency situations. All permanent concrete batteries and their locations are listed here. The Navigation links take you to the lists of forts & batteries, and to the entries for the individual locations and batteries. Fort and battery names used in this database are those being the last official designation. Every effort has been made to make this database as accurate as possible, but it will most likely contain a number of errors and omissions. We would greatly appreciate being contacted about any corrections. Click here for notes and abbreviations for the listings.

All maps & drawings on this site came from copies of materials in the holdings of the National Archives of the United States.

NOTE: PDF files with a collection of Reports of Completed Works (RCWs) of the Harbor Defenses built by the United States are now available as PDF files in a series of DVDs or CDs. See details on the CDSG ePress page.

The actual textual database entries for the three forts and 18 batteries of Harbor Defenses of the Columbia River have been completed (see the US Pacific Coast page, HD Columbia River).
