Gates galore

Gates to the city, to the palaces, to the major thorough fares, to mosques, and riads.  Gates in walls that are 18 ft thick. Wood gates, bronze gates. All gates with tile and plaster decoration. An interesting tidbit, per our local guide Hesham, in the olden days circa 800 AD, camel caravans all had to enter the city of Fez through one specific gate where all people and animals were examined by doctors. If any were sick, the individuals were denied entry. To keep the city healthy. They also exited through another gate where they had to prove they had paid any taxes owed. These two gates were called the kidney gates because of their filtering functions.
