Founded in 1856, the National Portrait Gallery is home to a large collection of portraits of famous people, dating from the Tudor period. Paintings include Henry VIII, Edward VI, William Shakespeare and Oliver Cromwell. Admission is free.
It's simple in its content, the gallery is full of portraits - from the royal family, celebrities and ordinary people from around the world.
My favourite room is the tudor room as its my part of history and its so calm. There are no muppet tourists and kiddies running around, pushing and shoving. Total bliss hiding there (and you cant talk on your mobiles!)
The exhibitions over the years have been great as well. I loved the Mario Testino one - you could see clearly why he is such a highly regarded photographer around the world. There is another fashion exhibition starting soon at the NPG with Mario photos again. It will have Kate moss in there (london seems to be obliged to show her photo everywhere), but i'm sure there will be other amazing photos to look at.
I haven't tried the cafe and restaurant but i hhave been to a party upstairs which was very ccool as you get to see over trafalgar sqaure athe south bank which is beautiful at night. IIf you have a chance to go up there, dp it just to see the view!
