Frequently Asked Questions

What are some features of First State National Historical Park?

First State NHP includes:

× Dover Green (Kent County) - Laid out in 1717, it was on the city of Dover's central square, known as The Green, that Delaware voted to ratify the U.S. Constitution. Throughout the years, it has also been the location of many rallies, troop reviews, and other patriotic events. Today, The Green remains the heart of Dover's historic district and is the location of the Delaware Supreme Court and the Kent County Courthouse. The Dover Green will be managed under an easement.

× New Castle Court House (New Castle County) The court house was the first capital of the state and its State House (1776-1777). In June, 1776, it is where both the state of Delaware was created when it separated from Pennsylvania and the legislature acted to become independent from Great Britain. In 1848, the principles of the Declaration of Independence were put to the test when abolitionists Thomas Garrett and John Hunn were tried here, found guilty, and fined for helping enslaved people emancipate themselves.

× Sheriff's House (New Castle County) - Built in 1858, the Victorian brownstone building served as , which sits behind the Court House, served as both the home of the sheriff and as the administrative site for the attached prison which, together with the adjoining New Castle Court House, served as the center of New Castle County's justice system. This structure is all that remains of the first county prison in Delaware. It was donated to the National Park Service by the State of Delaware for inclusion in the national monument.

× Beaver Valley (New Castle County) - More than 1,100 acres of woods and rolling pastures three miles north of Wilmington (220 of which are in Delaware County, Pennsylvania) including the Ramsey Farm, Upland Forest, scenic rock outcrops and wetlands along the banks of the Brandywine River. The property is historically significant to the early settlement in Delaware, and straddles and contains the demarcation line known as the "12-mile arc," which is a part of a circle drawn from the Old New Castle Courthouse establishing the boundaries of the British colonies of Pennsylvania and Delaware in the 17th century. In addition, the property still contains homes dating back to some of the first Quakers that settled the area with William Penn, and likely contains landscape patterns of these original Quaker settlement patterns which will be able to be established and identified within the cultural landscape. The tract was acquired by the Conservation Fund from the Woodlawn Trustees and donated to the National Park Service for inclusion in the national monument.
