LancasterHistory, 230 N. President Ave., Lancaster, will hold its first-ever Capital Day Celebration on Friday, Sept. 27, from 5:30 to 8 p.m.

Capital Day is a yearly reminder of Lancaster's importance during the American Revolution. For one day, on Sept. 27, 1777, Lancaster served as the capital of the United States. British troops had occupied Philadelphia on Sept. 26, forcing the Continental Congress to flee westward to escape capture and execution. The Continental Congress stopped in Lancaster, resting for an evening before continuing on the next day to York. Lancaster continued to be an important munitions center during the revolution and, from 1799 to 1812, served as the capital of Pennsylvania before the center of government was moved to Harrisburg.

Doors will open at 5:30 p.m. for music by Vivace Live Strings and a performance of "The Capital Day Song" by Leo DiSanto. Adam Zurn of Uncharted Lancaster will present "On This Day in History: Five-Minute History" at 6:40 p.m. LancasterQuiztory, a Lancaster County-themed trivia game featuring prizes, will be played from 6:45 to 7:45 p.m.

Activities available throughout the event will include an all-ages indoor/outdoor scavenger hunt, LancasterHistory museum exhibit access, a kids' station, and yard games. Fall-themed food and beverages will also be available, including the opportunity to make s'mores at outdoor firepits. All attendees will receive a complimentary coupon to redeem at FoxDuck's West King Street location for a free Capital Day poster for a limited time.

Those interested in participating in LancasterQuiztory may sign up on-site at the celebration before 6:30 p.m. Individuals and groups of up to six persons may participate as a team. For those not interested in joining for trivia, all other activities will continue during that time.
