2026 Memorial Illumination

Antietam National Battlefield will present the Annual Memorial Illumination on Saturday, December 5, 2026 to honor the 23,000 casualties from the Battle of Antietam on September 17, 1862.

The event is a driving tour open to the public starting at 6:00 pm. Cars enter the park by traveling west on Route 34 and lining up on the shoulder of the road. Drivers must be with their vehicles parked on the shoulder of Rt 34 after 5:00 pm. Any unattended vehicles parked on the westbound shoulder of Rt 34 after 5:00 pm, blocking the flow of traffic into the event, will be towed. Cars are allowed to enter the event until midnight. Walking is not allowed. Donations will not be accepted for this event.

Visitor services during the day will be limited and only porta johns will be available. The northern end of the park, north of Route 34, will close at 3:00 pm.

About the Illumination

One of the things that makes the Battle of Antietam unique is that it remains the bloodiest single-day battle in United States history. Over the course of roughly 12 hours, 22,720 soldiers were killed or wounded or went missing. That number is very hard to visualize or conceptualize for many. The Memorial Illumination provides a vivid visualization of the scale of loss at Antietam.

Origins

In 1989, Georgene Charles came to the park with an idea to emotionally connect visitors to those who were killed, wounded, or missing at Antietam. She proposed lighting luminaries—one to represent each casualty of the battle. In addition to the idea, Charles also worked hard to recruit volunteers and handled many of the aspects of arranging this massive special event. Her involvement continued for over 30 years. She was integral to this event becoming a reality and her legacy continues today.

Building the Luminaries

Around two weeks before the Illumination, a group of volunteers constructs the luminaries. For each luminary, volunteers place sand in a paper bag, insert a candle in a cup, and box it up with 19 others. Consistency in packing is important to ensure that we have the right number of luminaries in the display on the field. Typically, it takes around 100 volunteers about four hours to assemble the luminaries.

The candles that we use were specifically designed by the Root Candle Company of Medina, Ohio, with a long wick, which helps them to burn for 14 hours. In fact, they are known as the “Antietam” candle.

Timing

We hold the event in December to ensure that crops have been harvested from farm fields and to allow for the maximum amount of darkness for visitors to drive through the display.

 

Volunteers assemble 23,000 luminaries in one day a few weeks before the Memorial Illumination. They are then transported to the field and placed by more volunteers on the morning of the event. The candles are lit later in the afternoon.

Placement and Lighting

On the morning of the first Saturday in December, between 700 and 1,200 volunteers arrive to unpack luminaries, space them evenly throughout the fields, and light them. Many groups have designed tools over years of participating in this event that make their job of laying the bags in straight rows easier, including ropes with knots spaced at 15-foot increments.

Thank You to Those Who Make This Event Possible

Thank you to our volunteers, staff members, and partners who make this event possible. This monumental effort spans three days, and annually our volunteers donate over 5,000 hours of their time to make the Illumination possible. We thank them for their time and effort!
