Design idea (dialogue of cultures) The main idea of ​​the design of Austria Square is based on the thought of the presence of a garden in the city, in order to achieve design goals such as identity and presence, because the basic design of cities - or at least a part of cities in the past - can be found in the original design of the Iranian garden. The developments related to the palace of the cities, gardens and the structural relationship between the garden and the city are such that on the one hand the garden can be called the city and the city the garden, and on the other hand the garden can be considered as a workshop for city planning. The basis of garden organization in cities can be seen in the types of city garden, garden in garden, square garden and street garden. In such a way, citizens can be led to nature (garden) in the heart of cities. The Iranian garden consists of an entrance gate, a row of trees, and a water stream.
