A public square is an open space within a town or city, of a perfect or approximately square shape, or of a regular rectangular shape. A square is usually open for public intercourse, as in a market square or public square, but sometimes the center of the square comprises private grounds (as in the garden squares constructed in the high-class residential suburbs of west London in the 17th, 18th and 19th centuries).
In modern city planning, spaces set aside as open and public serve an important function amidst all the privately owned and built land.
