Riegelsville is a borough in Bucks County, Pennsylvania, United States. The population was 868 at the 2010 census.
Benjamin Riegel founded Riegelsville. The original, and now historic, Riegelsville Inn that he built in 1838 still stands. This historic stone inn has offered food and lodging to Bucks County travelers for over 160 years. The community was named for the Riegel family, as early landowners; they established paper mills across the river in New Jersey
Bucks County, one of the three original counties in Pennsylvania, was named after Buckinghamshire, England. Bucks County became the setting for George Washington and his troops to cross the Delaware River and attack Trenton, NJ. Catching the enemy by surprise, it was the turning point of the American War of Independence. With the completion of the Delaware Canal in 1832, the lands along the Delaware River attracted great industrial development. The movement of coal, a major important product of the area, brought capital & investment to Easton. Boats carried coal, stone, iron, crops and goods from the mills along the 60 miles from Easton to Bristol. Along Canal Street grew one of the largest industrial manufacturing centers of America during the 1830s and 40s. Easton continued to prosper as a center for industry, manufacturing, commerce, and culture at the Forks of the Delaware and along the great rail lines. Riegelsville prospered when the Delaware Canal opened in 1832 with warehouses and factories lining its banks. The canal closed in 1931 after 99 years of service and was replaced by the railroads. Today, Riegelsville is a peaceful and quiet town. Woods and fields border the Delaware Canal; remnants of crumbling stone foundations along its banks are reminders of a busy past.
