Columbia, formerly known as Wright's Ferry, is a borough in Lancaster County, Pennsylvania, situated on the Susquehanna River with a population of 10,222 as of the 2020 census. Founded in 1726 by English Quaker John Wright, the settlement grew around the eponymous Wright's Ferry, the first commercial river crossing in the region, which sparked territorial conflicts with Maryland but came within a few votes of becoming the new United States capital. Throughout the 19th century, it thrived as a transport and industrial hub, serving as the terminus of the Pennsylvania Canal and surviving a brief siege during the Civil War. However, the Great Depression and 20th-century economic and technological shifts caused a long decline. Today, it is renowned for hosting one of the world's few museums dedicated entirely to horology (the study of timekeeping), while also preserving historic landmarks like the Wright's Ferry Mansion (1738), the borough's oldest surviving house.
