Have you ever wanted to visit the former Irvine-Newbold estate but didn't know where to find it? Although the once-grand mansion, barns and outbuildings are long gone, here is an opportunity to tour the land that this fascinating estate stood upon at the Irvine Flats along the Allegheny River. The huge Greek Revival mansion was built by Callender Irvine in 1822, although additions and changes were made over the years. On the property there once stood large barns, a creamery, a carriage house, workers' or tenant houses, a green house, horse stables, a grist mill, a water tower, rock-walled flower gardens and even a private family cemetery. The ice house is still visible because it is partly underground. Sadly, when the last of the Irvine-Newbold family passed away, the house had fallen into disrepair. The National Forge bought the property but was unable to resell it. Over the years the buildings had begun to decay and had become a potential hazard to curiosity seekers. Everything was razed in 1973, but prior to the destruction, the National Forge commissioned an architect to build a scale model of the fabulous mansion and that model sits in the Irvine-Newbold Room at the Wilder Museum for everyone to view.
