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 Old Lyme’s 72.9 sits near the middle of its state (48% of Connecticut towns have fewer) while its 56 historic buildings outnumber those of 86% of U.S. towns.
