Antietam National Battlefield


Antietam National Battlefield was established in 1890 to commemorate those who fought in Sharpsburg, Maryland on September 17, 1862, the bloodiest single day in American military history with more than 23,000 total casualties.  In fact, it was in the aftermath of Antietam that Clara Barton earned her nickname “The Angel of the Battlefield” before going on to found the American Red Cross in 1881.  The battle was a draw, but together with a Union victory at Harpers Ferry stopped the Confederate advance north and provided the impetus for President Lincoln’s Emancipation Proclamation.

Must-Do Activity

Your entrance fee allows you access to the museum and eight-mile driving tour, as well as 3,200 acres of beautiful Maryland countryside.  Even though this site holds a grisly honor, today it is a charming open space with picturesque bridges and monuments, perfect for a pleasant walk or bike ride.  During our visit, Burnside Bridge was being rebuilt after it collapsed in 2014.  Overall, it is a much quieter spot than nearby Gettysburg National Military Park.

Best Trail

The park has more than doubled in size since 1990 and there are walking trails accessible all along the driving tour route.  At a minimum, you should get out of the car to walk “Bloody Lane” before climbing up the Observation Tower.

A split-rail fence provided cover for Confederate troops on Sunken Road, also known as “Bloody Lane.”  A nice view of it and the Maryland countryside is offered from the Observation Tower.
