Burgs are small, often informal communities or neighborhoods that can be found within larger cities or towns. They typically have a distinct character and may feature local shops, parks, and residential areas. The term is derived from the word "borough," which refers to a self-governing town or district. In some contexts, "burg" can also refer to a specific type of fortified settlement, especially in historical contexts. These settlements were often surrounded by walls for protection and were common in medieval Europe. Examples include Nuremberg and Heidelberg, which are known for their historical significance and architecture.
