There's not much I can say that others haven't already.
A stunning piece of Georgian architecture, and I'm pretty certain the occupants of the 30 terraced houses are sick of people fawning over.
Half covered in scaffold or tarpaulin, it makes you wonder it there's a local myth about the world coming to an end if it's ever completely devoid of work being carried out (like the Tower of London has a myth that if the Ravens ever all leave, the Monarchy will fall).
We stayed a good distance away, so we could take in the grandeur of the place.
However, at the end of the day, it's a row of houses - so you don't want to be too close to appear nosey.
Just a quick walk from the town, and worth the walk to see it.
