Alcune note sui cantieri e sulle tecniche costruttive a Roma nella seconda metà del XII secolo

Abstract

The study of the organization of the construction site and the diffusion of building methods in medieval Rome during the
12th century cannot be separated from an understanding of the political, historical, and administrative conditions of the city
during this period, as well as the early 13th century. The political-administrative structure and the relationship between the
population, the external territory, and the internal urban structure – along with the expansion of the urban district (Districtus
Urbis – played a crucial role in shaping the interplay between the urban and extra-urban contexts throughout the medieval
era. Studies conducted at the end of the 20th century focused on Roman construction techniques, emphasizing aspects such
as material procurement, transportation, and craftsmanship. The re-use of ancient materials in construction was widespread
in medieval Rome, with a significant presence of “archaeological quarries” where ancient monuments were dismantled for
new building projects. The transformation of technical and organizational processes at the end of the 12th century and into
the 13th century reflects broader political, social, and administrative changes in the city, with a notable shift towards the
specialization and regulation of construction labor.
