Hooper Battery was a hilltop earthworks fortification, built for the Defense of Cincinnati during the American Civil War in Northern Kentucky by the Union Army to turn back invading Confederate troops. It was constructed to protect Cincinnati and the Ohio River valley. The battery overlooks the Licking River valley in an advantageous position. Hooper Battery is one of 6 remaining artillery batteries from the 28 that were built on Northern Kentucky hilltops from 1861 to 1863.
