Monocacy National Battlefield
Fields, bridges, farms, and an auto tour place the 1864 Battle of Monocacy in its river landscape near Frederick.

Artwork inspired by John Ross Key
On July 9, 1864, Union forces confronted Jubal Early’s larger Confederate army at Monocacy. The battle was a Union defeat, yet the delay helped Washington prepare for Early’s advance. That tension between what happened on the field and what it meant strategically makes the landscape more than a set of monuments.
A visitor-center exhibit and five-stop auto tour spread the story over separate farms and river crossings. The Worthington and Thomas farms show different parts of the engagement; the Gambrill Mill boardwalk offers a river viewpoint. Best Farm also carries the history of enslaved people before the battle, a reminder that a battlefield has lives and labor beyond one day in 1864.
