Stone Mansion was built by Robert G. Woodside (1876-1964) to resemble his father's ancestral Irish cottage. Woodside was an attorney, decorated war veteran, founder of the VFW, co-chair of American Battle Monuments Commission, and Allegheny Co. Sheriff and Controller. He was awarded the Medal of Freedom by Pres. Eisenhower in 1954. Since 1990, Stone Mansion has housed businesses.
