Wednesday, 6 October 2011 - Wandered central London alone, photographing iconic architecture and landmarks including the Swiss Re ("Gherkin") and Heron Tower in the financial district, visited the Horse Guards parade ground and stables, watched the Changing of the Guard ceremony, explored the Household Cavalry Museum, wandered around the British Library neighborhood, and captured historic scenes near the Monument to the Great Fire of London and Leadenhall Market.
