Clayton Farm Heritage Museum is the former home of the Wiese family located off Naracoorte Road on the outskirts of Bordertown, South Australia. It consists of a group of historical thatched buildings and sheds, including the largest thatched structure in the Southern Hemisphere. The historic farm homestead dates back to 1885 with a woolshed dating back to 1901. Volunteers have spent over 20 years restoring the homestead, stocking it with a substantial collection of restored historical farm machinery and stationary engines.
