One of the most popular sites in the First State National Historical Park, the New Castle Courthouse Museum was where Delaware State declared its independence in 1776. It was built in 1732, making it one of the oldest courthouses in the country, and it also happens to be the first courthouse and state capitol in Delaware. It was declared a National Historic Landmark in 1972, and tours are available Tuesday through Saturday and on Sunday afternoons. Admission is free of charge, and visitors are also welcome to enjoy a leisurely picnic on The Green outside the museum.
