A large part of the magical appeal of the Luxulyan Valley has always been the water running in the leat system, once used to power the tramway and machinery on the Fowey Consols copper mine.

However, a recent survey revealed a new and very large leak from the base of the viaduct posing a serious risk to the footings of the masonry. Other water leaks have caused significant erosion of mortar from the masonry joints as well as encouraging vegetation to take root, causing still further damage to the joints and mortar. If we do not act quickly, the footings will be destroyed, ultimately leading to the collapse of the viaduct. The viaduct is a masterpiece of 19th century Cornish engineering, having been built to carry both a horse-drawn tramway across the valley and...
