The Oblong
This marker denotes the western boundary of Connecticut under an agreement reached in 1683 between Governor Thomas Dongan of New York and Governor Robert Treat of Connecticut.
Later the Treaty of Dover signed on May 14, 1731 moved the western border of Connecticut about two miles farther east to the present border between the two states, thus creating the area since known as “The Oblong” sixty miles long and approximately two miles wide extending from the southern border of Massachusetts to Long Island Sound.
Marker is on Quaker Hill Road (County Road 67) 0.2 miles west of Glen Arden Drive, on the right when traveling east.
