It was located on Bigelow Street (formerly Squirrel Hill Road) between Parade and Shields streets, and had cannons facing the Point, and trenches to protect soldiers.

The fort was one of the most massive of the 27 built at the time to defend Pittsburgh from the Confederates, and like the other forts, was built of mounds of dirt.{{cite web|url=http://www.squirrelhillmagazine.net/images/full-magazine-winter-2011.pdf|title=Squirrel Hillʼs Part in the Civil War|website=Squirrel Hill Magazine|archiveurl=https://web.archive.org/web/20120324045238/http://www.squirrelhillmagazine.net/images/full-magazine-winter-2011.pdf|archivedate=March 24, 2012|url-status=dead|accessdate=November 9, 2012}}{{cite web |url=http://wesa.fm/post/one-quiet-pittsburgh-neighborhood-home-civil-war-fort#stream/0 |title=One Quiet Pittsburgh Neighborhood Is Home To A Civil War Fort |date=May 31, 2018 |publisher=WESA}}

A powder magazine was also built nearby, on Beechwood Boulevard.

It remained standing until its demolition in 1928.
