The Madisonville site was the largest and most thoroughly studied village of the late Fort Ancient culture (AD 1450-1670). Artifacts were so abundant there that local residents called it the "pottery field." Between 1879 and 1911, a generation of Harvard archaeologists trained there. Dr. Charles Metz, assisted by Harvard University's Frederic Ward Putnam, excavated the remains of numerous houses, storage pits, and burials. The presence of glass beads and bits from iron kettles indicates these villagers may have been among the first native Ohioans to learn of the coming of Europeans to America. Mariemont street names Cachepot, Midden, Flintpoint, and Hammerstone are reminders of these earlier residents. The pavilion was designed by the noted town planner John Nolen in 1921, but not constructed and dedicated until 2001.
