City of

New Castle

Kentucky

Founded 1798

New Castle Kentucky is located in Henry County 35 miles northeast of Louisville, off I-71. Being one of the oldest cities in Kentucky, New Castle was settled in the 1790’s and became the county seat when Henry County was established in 1798.

With approximately 1000 people, New Castle is one of the smallest towns in Kentucky with a preservation district and is certified in both “Kentucky Main Street" and “Preserve America” Programs. We are very proud of our efforts to preserve our historical buildings and rural heritage.

New Castle has one of the few remaining intact 19th Century courthouse squares in Kentucky. Our homes and commercial buildings allow us glimpses of the rich architectural history of our city. A tractor on Main Street is as common as a car, truck, or school bus. This is what makes us a unique rural community.
