History

Madisonville site, the remains of a Fort Ancient village abandoned before Europeans settled in the area in 1786, is located nearby. There is also a pioneer cemetery adjacent to the Mariemont Community Church.

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.

However, the dream of welcoming all classes was not achieved in the end. Construction costs drove rents up considerably higher than those in the city that Emery had hoped to help others escape. Homeownership in Mariemont came with deed restrictions, including restrictions on occupants. “No lot shall be sold, conveyed, rented, leased or mortgaged to or occupied, except as a house servant, by a person of African or Asiatic descent.” While such restrictions were commonplace for the period, it is notable that the Mariemont Company adopted them, as they sit at odds with Thomas J. Emery’s documented record of philanthropy and advocacy, and with Mary Emery’s as well. Both supported African American causes, whether through funding segregated institutions such as orphanages or by pressing for the equal admission of Black and white students at the Ohio Mechanics Institute, making the company’s policies a striking contrast to their broader commitments.

In 2008, owing to its "unique character, compact and walkable design, and strong citizen participation and engagement", the American Planning Association designated Mariemont a "Great Neighbourhood".
