These photos were sent in by PH. He writes: "As everyone knows, the 2012 Olympic and Paralympic Games took place in London, UK in July-September. There were a huge number of visitors and consequently a large number of public toilets were provided. These temporary facilities had been constructed in small pods which were grouped together in strategic places around the park in large numbers."
"The first two photos were taken of urinals in the main Park."
"The third photo was taken of the urinals inside the concourse of the Olympic Stadium itself at the end of the evening session when everyone was going home."
