About New Castle

Perched along the Delaware River about six miles south of Wilmington, New Castle combines small-town quiet with deep history. With around 5,500 residents, the city features shaded brick sidewalks, a classic town green, and hundreds of preserved colonial-era homes. Delaware's first state capital met here in 1776, and today the community offers a relaxed, scenic atmosphere with an easy commute into Wilmington or Philadelphia.

Daily life here often centers around the riverfront, especially at Battery Park with its paved trails, picnic spots, and open water views. The town comes together for local traditions like the annual Separation Day celebration each June, while the Colonial School District and William Penn High School serve local students. With easy access to major highways, nearby job centers, and the New Castle Airport, it is a practical choice for anyone looking for historic character without giving up modern conveniences.
