Delaware

By Travelog Editorial Team ยท Updated August 8, 2026

Delaware is live on Travelog with one city, New Castle, a National Historic Landmark district. The New Castle Court House, built in 1732 and free to visit, is where Delaware's colonial assembly voted on June 15, 1776, to separate from both England and Pennsylvania. It's part of First State National Historical Park, the 400th unit added to the National Park System. Immanuel Episcopal Church on the Green, operating continuously since 1689, is the oldest Anglican parish in Delaware and the oldest continuously operating Episcopal parish in the country.

New Castle holds a specific claim most visitors don't expect, the site of Delaware's 1776 separation from both England and Pennsylvania, worth understanding accurately before visiting, covered in full below.
