New Castle Court House Museum

Located in the historic district of New Castle is the New Castle Court House Museum. Administered by Delaware State Museums, it is one of the oldest surviving courthouses in the United States and a registered National Historic Landmark Site. The original 1732 court was built over the remains of Delaware’s first courthouse of 1689, with additions and modifications throughout the 18th and 19th centuries. All jurisdictions of Delaware’s courts have met in the building including the Federal courts. The courts removed to the City of Wilmington in 1881 with the changing of the county seat.

 

The New Castle Court House was also Delaware’s first statehouse and meeting place of Delaware’s colonial and first State Assembly. In the Assembly Room, the legislature who met on June 15, 1776 passed a resolution to separate from Great Britain and Pennsylvania, creating the Delaware State. Two months later, September 20, 1776, the first Constitution for the Delaware State was adopted. In 1777, the capital moved to Dover.

The Court House cupola was designed in 1732 as the center of a 12-mile radial circular boundary, which created Delaware’s unique curved northern border.

 

Significant events took place at the New Castle Court House involving slavery and the Underground Railroad. Delaware’s most prominent abolitionist and station master on Delaware’s Underground Railroad, Thomas Garrett, assisted in aiding a runaway slave family to escape from New Castle to Pennsylvania. He and fellow abolitionist, John Hunn, stood trial before the Federal court seated at New Castle on charges violating the Fugitive Slave Act of 1793. The trial was presided by United States Supreme Court Chief Justice Roger B. Taney. Garrett and Hunn were found guilty and fined thousands of dollars, losing both homes, businesses and personal property. But here in the Court Room, Garrett would defiantly proclaim that he would continue with his efforts in helping those oppressed by slavery regardless of the cost.
