30 St. Mary Axe

Today I went to London for the Open House event. In the morning I worked as a volunteer in Horse Guards, guiding visitors around the cockpit and the Duke of Wellington's offices. Then in the afternoon I visited some buildings myself, including Tower 42 and the adjacent 30 St. Mary Axe. Here is a view from the upper viewing deck looking down to the lower floor.
