Just turn off of Potomac Street onto Springfield Lane to see why George Washington frequented Williamsport. Visit the museum located in the barn and operated by the History and Museum Board to observe first hand the rich heritage and history of Williamsport. The Barn, which overlooks Williamsport's Byron Memorial Park, was built circa 1755 by Otho Holland Williams, the founder of Williamsport. The Town of Williamsport purchased this barn in 1987. This eight bay frame barn is 56 feet wide and nearly 168 feet long with a raised-seam roof. The first section, built over 200 years ago and set on stone foundations, is a four-bay bank barn with two open brick granaries. One of these has simple open brickwork ventilation holes. The other four bays were built somewhat later and in the 1880's, Victorian trim and nine ventilators were added along the ridge of the roof. Within the barn, the original cedar shakes are still visible.Williamsport is working to preserve the barn's historic past and make it a part of our present community life.
