Preston Mill & Phantassie Doocot

Preston Mill stands on the River Tyne at East Linton, a rubble-built watermill with a curious conical Dutch-style kiln roof that has drawn painters for a century and Outlander's cameras more recently. Parts of the building may date from the 16th century, and it ground oatmeal for local farms until 1959, the last working watermill in East Lothian; the National Trust for Scotland keeps the wheel and machinery turning on guided tours that tell of the miller's floods, mice and dust. A riverside walk crosses to Phantassie Doocot, a 16th-century beehive dovecot built for 500 birds, with kingfishers, mergansers and herons along the way. Reviewers say the tour is essential and praise the guides for pitching the detail just right. Tips from visitors: book a tour slot online, the mill runs Thursday to Monday from spring to October, the last Sunday of each month is a quiet day with the machinery still, and dogs are welcome on leads in the grounds.
