A town square (or public square, urban square, city square or simply square), also called a plaza or piazza, is an open public space commonly found in the heart of a traditional town or city, and which is used for community gatherings. Related concepts are the civic center, the market square and the village green.
Most squares are hardscapes suitable for open markets, concerts, political rallies, and other events that require firm ground. They are not necessarily a true geometric square.
