“This is the standout building of its time…What greater evidence of the vision of the men who shaped Western Pennsylvania, formed its industrial base and established its civilization could there be than this great house.”


– George Thomas, PhD Clio Group, Inc.


Construction began on the Meason Mansion in the late 1790s and was completed in 1802 for Isaac Meason – one of America’s first successful industrialists and Colonel in the Revolutionary War.


The manor graces the site where, in 1774, George Washington held council with Native Americans from six different nations. In 1990, the estate was deemed a National Historic Landmark – one of only 2,000 in the entire country. Today, the mansion is renowned by the nation’s leading preservationists and is considered to be one of the greatest homes in the nation.
