HistoryA character grade: shown, never part of Lewes’ overall grade.
Delaware towns list more on the Register than most of the country (a typical Delaware town has 29.4 per 10,000 residents, the U.S. 2.4), so Lewes’ 1,997 sits above most of its state (100% of Delaware towns have fewer) while its 700 historic buildings outnumber those of 98% of U.S. towns.
NoteThe founding year comes from Wikidata alone; no second source gives 1631.
