HistoryA character grade: shown, never part of Mariemont’s overall grade.
Ohio towns list about as much on the Register as the country (a typical Ohio town has 2.9 per 10,000 residents, the U.S. 2.4), so Mariemont’s 3,428 sits above most of its state (100% of Ohio towns have fewer) while its 1,191 historic buildings outnumber those of 99% of U.S. towns.

Mariemont was founded by Mary Emery and planned by John Nolen and 25 leading American architects. Emery and other dignitaries broke ground on April 23, 1923. Emery had spent around seven million dollars of her own money to purchase the land that would become Mariemont. Her vision was of a planned community reminiscent of an English garden city that would welcome people of differing economic backgrounds, with a mix of single-family homes and affordable low-rise apartments.
