The National Trust have a fantastic exhibition at Tattershall Castle, Lincolnshire; "The House Of Bling".
The castle has literally been taken over by contemporary artists to create a stunningly elloborate showcase of work.
Each piece is installed within the rooms or grounds of the castle, with the aim to directly engage the visitors who will be able to get up close to the installations and even interact with the art itself.
Keen visitors can inlist as volunteers, perhaps as exhibition guides or to help install the artworks alongside the artists. Workshops are also running throughout, truely worth a visit!
From Sat 8th August to Sun 23rd August 2009
