550 S Dupont Pky,
New Castle,
DE
19720
New Castle carries more than three centuries of history within its four square miles, sitting on the Delaware River just six miles south of Wilmington. Originally settled in 1651 by the Dutch West India Company under Peter Stuyvesant, the city became one of the earliest permanent European settlements in what is now the United States. That heritage is still visible today in the brick-lined streets, colonial-era architecture, and the quiet confidence of a place that knows exactly what it is.
Life here moves at a measured pace while remaining genuinely connected to a major metro area. Wilmington's business district, corporate campuses, and financial sector employers are a short drive away, making New Castle a practical base for those who want a smaller-scale setting without sacrificing access. Battery Park stretches along the riverfront and serves as a natural gathering point throughout the year.

We also advise parents to visit schools, consider other information on school performance and programs, and consider family needs as part of the school selection process.
