Bretton is a hamlet at the top of Eyam Edge. The photograph shows the 'Barrel Inn' which is the highest pub in Derbyshire. It's not the highest pub in The Peak District though, that's 'The Cat And Fiddle Inn' in Cheshire.
To the north is 'Bretton Clough' a deep wooded valley. Many years ago I stumbled as I was descending into the clough and severely sprained and twisted my ankle.
One convenient thing about The Barrel Inn is that the toilets are just inside the doorway so it's easy to pop in without being noticed.
