This square was laid out in 1717 in accordance with William
Penn's orders of 1683, and has changed little since then.
One of the nation's most historic sights, it was here that
Delaware voted to ratify the U.S. Constitution, making
it the first state to do so. The Green was the site of early
fairs and markets when Dover was the county seat and then
state capital. It now hosts political rallies and public
events such as Old Dover Days in May, when many private homes
and buidings are open to the public. Free.
