National Historical Park
Famous as the First State to ratify the Constitution, Delaware was born out of a conflict among three world powers for dominance of the Delaware Valley. From this beginning, the region developed a distinct character that tolerated diversity in religion and national origin and valued independence.

Each fall, an 18th Century Market Fair is recreated to commemorate the original purpose of The Green.
