East Petersburg Borough is located three miles northwest of Lancaster and has a population of about 4500. It offers both new and established homes.

All major conveniences can be realized without having to venture far from the home. One of the highlights near the Borough is Roots Market located on Graystone Road just off Route 72 which is the major artery passing through the center of town. The market is open year round every Tuesday from 9am to 9pm and just about everything imaginable can be found there. It attracts tourists as well as the local people.

There is an open pavilion and community center (with a kitchen) available for meetings. There is also a community swimming pool with a playground on Graystone Road.

East Petersburg Borough was just 50 years old in 1996, but the community's roots date nearly to the time of the American Revolution. In fact, a farmhouse near the eastern end of the borough was built before the war and a nearby mill was already producing grain.
