Questions about Rosetta
Is Rosetta on the National Inventory?
Yes: rated Regional (record 20868102).
Can you visit Rosetta?
Many historic buildings are private homes; this one can be seen from the street.
When was Rosetta built?
Its National Inventory record dates it to 1780–1820.
Is Rosetta 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.
