[4] Terre Hill has the second fewest residents of any incorporated borough in Lancaster County, with the exception of Christiana.

The four-way stop was created during the closure of a section of PA Route 625 for underground pipe work.

According to the United States Census Bureau, the borough has a total area of 0.46 square miles (1.2 km2), of which 0.3 acres (1,046 m2), or 0.09%, are water.

These special events are sponsored by the fundraising group Terre Hill Days Committee.

Some events include Breakfast & Yard Sales in the Park, Lunch in the Park, Ice Cream Social, Terre Hill Community Auction, Christmas Decorating Contest, Santa's Workshop, and a Community Egg Hunt.

In 2007, the borough celebrated its centennial year with a special Terre Hill Days festival.

During this festive event, the entire Park is converted into a Christmas wonderland- lights, live music, food, entertainment, and more.

In 1980, Calvin Trillin wrote a humorous article in The New Yorker about a dispute between the fire company of Terre Hill and its ladies' auxiliary.
