In the 17th century were functioned in England two types of public spaces: piazza type of squares, devoid of plants’ composition and green city squares of a garden nature, designed for the residents of the nearby houses. Both of these presented the high-class type of public space, which with the time became popular in many cities in Europe. The aim of the paper is to define the importance of these arrangements in urban landscape, including the identification of functions which they perform today in urban tissue of cities.
