Urine Deflector Shield

Today I took a walk down Fleet Street and came across this curiosity - the Urine Deflector Shield!
Clifford’s Inn Passage, just off Fleet Street in the 19th Century afforded a dark and secluded area for a gentleman to relieve himself having drunk copious amounts of ale in the neighbouring taverns.  The owners of the buildings did not like their walls washed with urine so they erected deflector shields which would guide the urine to the gutter or worse cause the liquid to be splashed back on to the urinator and thus deter him from activity.
