Welcome to Delaware

The second-smallest U.S. state at 9 miles long and a maximum of 35 miles across, Delaware is known as the First State because it was first among the original 13 states to ratify the U.S. Constitution on December 7, 1787. The state’s many historic sites include colonial-era cities like the old grain port of Odessa with its pristine 18th-century buildings, the original 1802 Du Pont Company gunpowder mill on the Brandywine river, and the grand Du Pont mansions of Chateau Country near Wilmington. Many quaint port towns amid miles of sandy beaches along Delaware Bay and the Atlantic Coast, the Amish Country west of Dover, and great regional food and drink make Delaware a fun destination.
