Staircase to where?...
The great Hall at the Natural History Museum is more like a Cathedral than a museum. This is a picture of the stairs that take you to the top of the building. The view from the stairs inward to the building is very impressive indeed. you can view the picture I took of that in the comments.
When I went to take pictures of the building I spent amore time taking pictures of the architecture than looking at the exhibits. I think any photographer would find it hard to spend more time looking at the exhibits than taking pictures there.
