A modern information board on the east side of the City Mills near the Lade gives full details of the importance of the Lade and the City Mills. (This information board was sponsored by the Perth Civic Trust.)
There were almost certainly mills on this site in the 12th century. Commercial activity continued until 1966.
Until fairly recent times the importance of the Lade was confirmed by the annual inspection carried out by members of the Town Council.
The buildings were restored by Perth and Kinross Council between 1982 and 1988 and became a working mill again for some years. There is a plaque inside the Mill commemorating this. Later it housed Perth Tourist Information Centre. The buildings are now used by Perth and Kinross Heritage Trust and are occasionally open on Doors Open Days. Plans to open up as a working mill and visitor attraction were sadly abandoned in 2023.
