Geologia, tempo e abito urbano (Imago urbis)

The surfaces identify towns, particularly those with a long history, they talk about their different phases of construction, their relationship with the territory, the passing of time. In fact in the past centuries the materials used to build towns and villages were almost exclusively those found locally. Each territory was characterized by its own building materials, its own techniques for the superficial processing of materials, its own renders and its own painting. In the territory of the Italian peninsula, thanks to the great geological variability and the presence of little states, that lasted until the second half of the XIXth century, these differences are particularly evident and this is why we can speak of the urban habit of every town. In this text we will examine how the nature of the territories influences the urban habit with particular attention to Tuscany.
