Thompson House and Mill

Queensborough was established when Miles Riggs and his wife Hannah arrived here and built a sawmill and flour/feed mill. Lumber camps further north would send log drives down the Black River, helping the mill and the community to thrive. This handsome regency-style frame home was built in the early 1850s for Riggs’s family, which included 11 children. Peek inside only!
