The Estill Log Cabin originally stood just north of the intersection of Clayton Road and Bopp Road and, at the turn of the 19th century, formed part of the main house of Frank C. Reilly's 400-acre working farm, Hill Top Farm, which extended north to what is now Conway Road. Historians think the cabin was built sometime between 1870 and 1880, and it was later enclosed by a more modern structure. In 2003, owner Harry Estill, a descendent of Frank C. Reilly, worked with Jesse Francis, a curator and restorationist with St. Louis County Faust Park, the City of Town & Country, and community volunteers to disassemble the two-room log cabin and reassemble it in Drace Park with aid from a grant from the St. Louis County Municipal Grant Commission. Jessie Francis tagged the logs and documented their arrangement for reconstruction, and Wheelock Crosby Brown, a Trans-Mississippi architectural historian, donated similar hand-hewn logs to replace some that had been damaged by termites. The cabin was reconstructed near the existing Kropp Log Cabin in Drace Park, and its windows and doors were purposely not replaced so visitors could walk through it and get a feel for life in a small log cabin. The Town & Country Parks and Trails Foundation also helped raise funds beyond the grant amount needed to complete the project.
