Britain abounds with museums and art galleries. The British Museum and the National Gallery in London, are world reknowned and are indeed treasures, but every major town has at least one, usually free of charge. Everywhere you go there are small museums illustrating a particular aspect of British life.
All the major cities, and some of the smaller ones too, have theatres and concert halls. The West end shows go "on tour" across the country and this is often a less expensive way of seeing a new production. Smaller theatres may offer less commercial productions for the discerning theatre goer.
In the height of Summer many stately homes and castles also host open air events which provide great opportunities for grand picnics! These include concerts of all types of music (often accompanied with fantastic firework displays), plays, and mock battles!

There are also regional events, such as the Scottish Highland Games, (a mixture of sport, music and dancing) and Country shows which feature traditional country activities and much more these days.
