Upper Mill or Walton Mill is a Grade II listed smock mill at Walton, Suffolk, England, which has been conserved. History Upper Mill was built in 1804. The mill was dismantled in the early 20th century leaving the empty smock tower standing. The mill was on the Buildings at Risk Register in 1995 but repairs have since been carried out to the weatherboarding to ensure the mill's survival. Description Upper Mill is a two-storey smock mill on a two-storey brick base. It had four Patent sails and the boat-shaped cap was winded by a fantail. It had two pairs of millstones.
