The Casemates of Old Fort Niagara
historic place
At Old Fort Niagara in Youngstown, New York, stand the Casemates. These structures were built between 1863 and 1872. During the American Civil War, the Union reinforced Fort Niagara's earthwork walls with concrete and brick. This was due to concerns over British Canada. Designed to house 24-pounder cannons, the Casemates were never armed. By their completion, these defenses were obsolete. The specific historical marker text for the Casemates, and the year it was erected, are not available. The Casemates reflect military preparations at Fort Niagara during a time of national concern.
