Although often overlooked, the small state of Delaware really packs a punch with its historical significance. The first state to ratify the United States Constitution is home to a number of quaint towns that are well worth a visit if what you're looking for is a glimpse back in time, and Odessa is top on our list. As one of the oldest towns in Delaware, Odessa dates all the way back to the 1660s when the area first became a Dutch settlement. The Federalist architecture and gorgeously restored homes that draw visitors today are a result of the hamlet's riverside location, which made it an important grain shipping port after the English took control of the area in 1664.
