Mac-O-Chee Castle was built by journalist, politician, and diplomat Donn Piatt for his first wife, Louise. The towering landmark in the rural countryside of Logan County, Ohio was designed by John L. Smithmeyer, who was the initial superintendent in the building of the Library of Congress. Mac-O-Chee Castle was completed in 1881 and was designed as a grand residence of the Piatt family, who was well known in society. They spared no expense in creating a home that reflected their wealth and status. Mac-O-Chee Castle is characterized by its Victorian Gothic Revival style, featuring ornate details, turrets, and pointed arches, which were popular in the 19th century. The Piatt family also had a deep connection to the local Native American history, and this is reflected in the name they chose for their estate. The castle is listed on the National Register of Historic Places.
On October 19, 2019, Mac-O-Chee Castle was purchased by the Cole family in order to preserve the historic landmark and keep it accessible to the community and public for decades to come. As one of Ohio’s most iconic landmarks, Mac-O-Chee Castle continues to captivate visitors with its fascinating history, stunning architecture, and timeless beauty, serving as a testament to the enduring legacy and the rich heritage of the region.
