Haddon Hall, Lower Courtyard
Haddon Hall is built around two courtyards, this one is open to the public, the Upper one is not. Lord and Lady Edward Manners live here, so that part is private, although you do sometimes see them round the public areas with their dogs.
Haddon Hall is one of many impressive old stately homes in the Peaks and Derbyshire, but is unique in being remarkably well preserved in it's original state. It was unoccupied from 1700 to 1920, so whereas other houses were largely modified or damaged by fires this house still has many of it's medieval and Elizabethan features in tact. There is just a bit of dodgy 1920's wiring and bakerlite light switches here and there.
It's definitely well worth a visit, although it is expensive (as all historical homes are).
