Connecticut towns list more on the Register than most of the country (a typical Connecticut town has 73.3 per 10,000 residents, the U.S. 2.4), so Marlborough’s 4.9 sits below most of its state (2% of Connecticut towns have fewer) while its 3 historic buildings outnumber those of 65% of U.S. towns.

What stands out about Marlborough’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The earliest inhabitants of present-day Marlborough, prior to the arrival of the English settlers, were the Podunk people, an indigenous people who spoke an Algonquian language. The town's origins can be traced back to 1648, when (John) Sadler's Ordinary, a rest stop from the colonical era, was established. This establishment, the second of its kind in Connecticut Colony after Hartford, served as a crossroads during colonial times. Travelers would stop to rest at the Buell House (now the Marlborough Tavern) located at the heart of what is now Marlborough center. 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 continues to operate today.
