This is a tour of invisible things… things you can’t see because they’re now gone, because they’re closed off or underground or because they've just always been invisible. From lost sounds, through the smells of a sewage scandal, to a timber-framed mansion with orchards, this walk along the Ashton Canal and its surroundings will encourage you to linger a little in a part of town people tend to pass through. We hope it will make you appreciate the rich layers of history that have shaped Holt Town.
