Although the original Sadler's Ordinary (Inn) eventually went out of business, a new Sadler's Ordinary was built in a new location in 1970, and is still in business today. Formerly a crossroads of sorts, travelers would stop to rest at the heart of what is now Marlborough center at the Buell House (now the Marlborough Tavern) during colonial times, and eventually a petition was filed to the colonial government to form an Ecclesiastical Society in 1747.  Marlborough was incorporated on 13 October 1803 with land from parts of three neighboring towns: Glastonbury, Colchester ( New London County) and Hebron ( Tolland County).   The town took its name from Marlborough, Massachusetts.  A complete town history called Reflections Into Marlborough's History was published in 2007.
