A tall cylindric room cratered with little holes in which the pigeons nest. The pigeon coop is actually a part of the post office and is located directly next to it. The post officers don't like pigeons, and like their excretion even less.
They often plot to get rid of the pigeons.
The pigeons are used as a means of communication with the other side of town in case of emergencies, as racing pigeons (see the gamel) and when they have outgrown their use, as food.
