DeWitt Log House or the Zachariah Price DeWitt Cabin, east of Oxford and north of Trenton-Oxford Road (Ohio 73), was added to the National Register of Historic Places in 1973. "Built in the wilderness about 1805, the log house of Zachariah Price DeWitt is now the oldest remaining structure in Oxford Twp.," reports the Oxford Museum Association. "It also is the last of a string of pioneer homesteads established along Four Mile (Tallawanda) Creek before Oxford Twp., the town of Oxford or Miami University even existed. It stands on the east bank of the creek about 500 yards north of Ohio 63. It is on Miami University land, leased to the Oxford Museum Association, which in 1973 took on its restoration to preserve this rare example of early 19th century log construction." The web site of the Ohio Historic Preservation Office (OHPO) of the Ohio Historical Society says "the craftsmanship and care put into the house exemplify the high quality of construction and detail. The land upon which the cabin stands is part of the 2.5 sections of land in the township settled before Miami University was founded and not deeded to the university in 1809." The land was to the university as part of the largely natural Bachelor Estate. OHPO says "Zachariah Price DeWitt was one of the first settlers in Oxford, and throughout his life was instrumental in community activities. He was a leading member of the early Baptist Church, and was secretary to the Ancient Free and Accepted Masons of Oxford (chartered in 1823) for many years. He was the second treasurer of Oxford Township in 1813, overseer of the poor in 1811 and 1813, and supervisor of roads in 1813. He owned and operated the sawmill, a vital part of early American life. He came to the aid of his country in the War of 1812 when he commanded a company of riflemen from Butler County which went to Detroit to assist Gen. Duncan McArthur. He built the original sections of the present Beta Theta Pi and Phi Delta Theta fraternity headquarters in the 1830's. After the DeWitts ceased residence in their cabin, it continued as a residence until the mid-20th century when it was used as a barn for a nearby house."
