Mezuzah on the Gate of Zion

The Mezuzah should be placed on the doorposts of the house, and in every room therein. A place serving regularly for unclean use, such as a bathroom, is exempt from Mezuzah. The Mezuzah should also be affixed on gates leading to communal places, even on gates of cities, symbolizes the sovereignty of the commandments over the Jewish social and communal life in all its aspects.
