====  On the other hand, when the urban planners are going to design the organization of a city, they must take into account the public services, communication ways (including railways),  as well as natural factors such as groundwater levels or seismic zones,  etc; for designing slopes,  retaining walls, embankments, bridges, etc…  ====  The main purpose of architecture is living because the buildings are shelters which protect us from exogenous factors, such as climate.
