Fort Delaware

Fort Delaware was built as part of the Third-System of coastal fortifications beginning in 1833 to protect Wilmington and Philadelphia.

As of 1851, it was intended to be armed with thirty-two 42-pounder guns, thirty-two 32-pounder guns, fifty-four 24-pounder guns, twenty flank howitzers, ten 8" heavy seacoast howitzers, one 13" mortar and two 10" heavy mortars for a total of 151 guns.

It was used as a prison camp for most of the Civil War. There are tours available. One of the highlights is shooting a coffee can with cement in it. The fort has also been reputed to be haunted and was featured on several episodes of the Sci-Fi channel series "Ghost Hunters"
