Questions about Ashtown Mill
Is Ashtown Mill on the National Inventory?
Yes: rated Regional (record 11362067).
Can you visit Ashtown Mill?
It can be seen from the street; whether you can go inside depends on its owner.
When was Ashtown Mill built?
Its National Inventory record dates it to 1800–1840.
Is Ashtown Mill protected?
Being on the National Inventory or the Sites and Monuments Record is a record, not protection by itself: buildings are protected by their council’s Record of Protected Structures, which each council keeps and no national open list gathers, so this page can’t say which are on it.
