So many of York's important buildings were under scaffolding on my last visit (Phoebe the cat lives in York).
St William's College.
The Mansion House.
With photograph. (To show you what you are missing.)
And many many more..
Inluding the Minster which always was and always will be partially covered in scaffolding. It's essential work and it is good that the money can be found for conservation though it must be a bit frustrating for visitors who have come especially to see the architecture.
The east end of the Minster has been covered in scaffolding for many years while the restoration and conservation of the largest expanse of medieval stained glass in the world was carried out. It is wonderful to see it uncovered again.
