Ben...I kept putting off the War Rooms too, because I just do not have that nostalgia for WWII that so many seem to have today, but when I finally went, it was...Why did I wait so long? Of course, London having been bombed during WWII, the war is still very much alive there in the national consciousness and much more intimate. I also found St. Paul's quite moving in that respect...there is a fabulous photo of the Dome of St. Paul's emerging out black clouds of bomb smoke. It is now commemorated on my fridge in the form of a magnet.
Joy's right, Der Brucer, the London Dungeon on the South bank of the Thames in an area known as Southwark, I believe. It's amusing...
I've never done Pollock's Toy Museum, but I hardily recommend the Theatre Museum in Covent Garden and the tour of the National Theatre...both a must for any theatre buff's. And the Actor's Church in Covent Garden-- another St. Paul's Church, designed by Inigo Jones. It's full of plaques and benches commemorating actors gone on to their reward.
I want to do a tour of the Haymarket Theatre as well, which is my favourite theatre in the West End.
Now I'm getting excited; I've been plotting this week our annual jaunt to London in a few months. so now I'm even more fired up.
