Built in the 1790s
Washington served until 1797 and John Adams followed him. Congress placed the permanent capital on the Potomac and the new city was surveyed in 1791. The first federal census counted just under four million people in 1790, and the cotton gin of 1793 changed farming across the South.
182 places on the National Register have a construction year in the 1790s on record. They stand in 26 states and territories. 10 are National Historic Landmarks.
Construction years come from Wikidata, matched on National Register reference number. Only plain four-digit years are counted, so a place recorded as circa or as a range is left out. Data refreshed September 19, 2026.
