I've visited some real time capsules in my time, but this one ticks almost every box imaginable. Fabric was produced at this mill as far as back as the late 17th century, and was once the driving force behind the local community producing the highest quality tweed. Its protection from the outside world is thanks in part to the flowing water that prevents it from being easily accessed - only by using fallen trees as a walkway can you get to see the treasures up-close.
