an interactive muster roll of Continental soldiers encamped at Valley Forge, ranger-led gallery programs and walks, a storytelling program, a photo gallery, a visitor information desk, and a store for books and souvenirs. 90-minute bus tours of the park and bike rentals are available seasonally. A short 18-minute film, "Valley Forge: A Winter Encampment" is shown in the park's theater next door. The visitor center, built in 1976, underwent a renovation starting in 2018 that was nearing completion in mid 2021, by which time it was partially reopened. During renovation visitor center operations moved to a temporary visitor center, located in the parking lot of the existing facility. The second phase of the opening, slated for fall of 2021, will include a new theater building and new interpretative and museum exhibits. Headquarters buildings A key attraction of the park is the restored colonial home used by General George Washington as his headquarters during the encampment. Rehabilitation of the headquarters area was completed in summer 2009, and included the restoration of the old Valley Forge train station into an information center, new guided tours, new exhibits throughout the landscape, and the elimination of several acres of modern paving and restoration of the historic landscape. Quarters of other Continental Army generals are also in the park, including those of Huntington, Varnum, Lord Stirling, Lafayette, and Knox. Varnum's quarters is open on weekends during the summer. Reconstructed works and buildings Throughout the park there are reconstructed log cabins of the type thought to be used during the encampment. Earthworks for the defense of the encampment are visible, including four redoubts, the ditch for the Inner Line Defenses, and a reconstructed abatis. The original redoubts and several redans on Route 23, Outer Line Drive, and Inner Line Drive were covered with sod to preserve them, but they are currently in need of further restoration. The original forges, located on Valley Creek, were burned by the British three months prior to Washington's occupation of the park area. However, neither the Upper Forge site nor the Lower Forge site has been reconstructed. There are also several historical buildings that have not been made open to the public because of reasons such as their current state of disrepair. These include: Lord Stirling's Quarters, Knox's Quarters, and the Von Steuben Memorial. Other historical buildings include the P.C. Knox Estate, Kennedy-Supplee Mansion and Potts' Barn.
