f you don't know, I used to work at Nottingham castle and on a frequent basis had people asking "Where's the castle?" as they expected the towers and turrets of Hollywood fiction. Also "Where did Marion/The Sherrif/Robin live?" and "Where are the dungeons where Robin was kept?" We would try and give a potted explanation that it's all a lot of stories and legends rolled together from different time periods, and if you really want a Robin Hood hat the gift shop is over there thankyuvermuch.
There are plans to revamp the castle, taking advantage of, and explaining (finally) all that stuff, and using it as a way to link from the legends into the real events and times that spawned and changed the myth (hating the Normans, mocking religious figures, viscous tax collecting needed for Richard's wars, etc). The castle really needs some TLC and this will tap into why a lot of people visit, while also steering them to discover and appreciate the genuine history and stories.
And now, plans near Sherwood Forest for... this!
