Neighborhoods in old Persian cities often formed around shrines of popular saints. All public facilities such as baths, houses of mourning (tekyehs), teahouses, administration offices, and schools were to be found within the neighborhood itself. In addition to the main bazaar of the city, each neighborhood often had its own bazaar-cheh as well (i.e. “little bazaar”), as well as its own ab anbar (or public water reservoir), which provided the neighborhood with clean water. Qazvin, for example had over 100 such reservoirs before being modernized with city plumbing in modern times.
