Washington Memorial Chapel and National Patriots Bell Tower carillon sit atop a hill at the center of the present park. The chapel is the legacy of W. Herbert Burk. Inspired by Burk's 1903 sermon on Washington's birthday, the chapel is a functioning Episcopal Church, built as a tribute to Washington. Burk was also instrumental in the development of the park, including obtaining Washington's campaign tent and banner, which used to be on display in the visitor center but is now in the Museum of the American Revolution in Philadelphia. The chapel and attached bell tower are not technically part of the park but serve the spiritual needs of the park and the community that surround it. The bell tower houses the Daughters of the American Revolution Patriot Rolls, listing those that served in the Revolutionary War, and the chapel grounds hosted the World of Scouting Museum. Memorial markers Sitting atop a hill at the intersection of the Outer Line of Defense with the Gulph Road, the National Memorial Arch dominates the southern portion of the park. It is dedicated "to the officers and private soldiers of the Continental Army December 19, 1777 – June 19, 1778." The arch was commissioned by an act of the 61st Congress in 1910 and completed in 1917. It is inscribed with George Washington's tribute to the perseverance and endurance of his army: The drive is lined with large (~2 m high) memorial stones for each of the brigades, or "lines", that encamped there. Crossing Gulph Road at the arch, the drive proceeds through the Pennsylvania Columns and past the hilltop statue of Anthony Wayne on horse. More brigade stones line Port Kennedy Road. Mount Joy Observation Tower Atop Mount Joy, the highest elevation in the main park area, stood a steel observation tower. The tower was closed in the 1980s because of deterioration, liability concerns, and the surrounding trees outgrowing the platform. The tower was removed and shipped to a private area near Wellsboro, Pennsylvania, where people can still climb it. The area where it stood is now only accessible by foot trail, the roads have been removed and the area is being given back to the woods. Trails There are of hiking and biking trails within the park, such as the Valley Creek Trail and the River Trail. The main trail is the Joseph Plumb Martin Trail, which encircles 8.7 miles of the
