What is patron city?

A patron city is a city that is considered to be the protector or guardian of a particular group of people or a specific cause. The term "patron city" is often used in religious contexts, referring to cities that are believed to be under the protection of a particular saint or deity. For example, Rome is considered the patron city of Catholicism, as it is the seat of the Catholic Church and the home of the Pope. Other examples include Athens, Greece, which is considered the patron city of learning and philosophy, and Jerusalem, which is considered the patron city of Judaism and Christianity.

In some cases, a patron city may also be associated with a particular industry or trade. For example, Detroit, Michigan, is often referred to as the patron city of the automotive industry, while Hollywood, California, is considered the patron city of the film industry.
