Intercourse - the village in Lancaster County, PA

Formerly known as "Cross Keys", this village was founded in 1754. The name was changed to Intercourse in 1814. There are several explanations concerning the origin of the name of Intercourse, but none can really be substantiated. The first centers around an old race track which existed just east of town along the Old Philadelphia Pike. The entrance to the race course was known as "Entercourse". Some suggest that "Entercourse" gradually evolved into "Intercourse".
Another theory concerns two major roads that crossed here: the Old King's Highway, whichran from Philadelphia to Pittsburgh (now called the Old Philadelphia Pike), and the road from Wilmington, Delaware to Erie, Pennsylvania. The intersection of these two roads was thought to be the basis for the town of "Cross Keys" or, eventually, "Intercourse".

A final idea comes from the "old english" language which was is use in the early 1800's. It refers to the "fellowship" or social interaction and friendship which was so much a part of an agricultural village and culture at that time. These roots mark the community of faith to this day, and the many evidences of it are experienced by those who care to dig a bit more deeply while visiting this area.
Intercourse is a town full of delightful treasures and friendly shopkeepers, nestled among the scenic Amish farmland. For visitors of any age, there's plenty to do in Intercourse. Enjoy your visit!
