Yesterday, we started out by heading over to St. Paul's, and climbing up into the dome ( The Whispering Gallery on the inside, the Stone Gallery on the outside, and finally the Golden Gallery on the outside of the very top of the dome, reached via some twisted passages between the inner and outer domes.).
After that, we headed over to Greenwich, and spent a few hours at the park. Most of the Observatory Museum was closed due to a huge set of improvements, new exhibits, etc which should be done in 2 years.
After that - it was off to the National Theater to watch The Artisocrats - a play about the last failing days of a once great noble family.
