Abstract

The presented research focusses on the first establishment urban map of the nineteenth century Gregorian Cadastre of Bologna, kept today at the National Archive of the city. In this cadastral cartography the city is divided into some sectors; for each sector – unique case in the Gregorian Cadastre – there are ground floor maps and maps for the floors above (5 floors) and below (2 floors). The present study aims to acquire a deep understanding of this rare multi-storey arrange-ment of the cadastral maps, focusing on a little but special group of cadastral lots in the centre of the city. By means of the graphical information stored in the georeferenced maps, coupled with the written one in the cadastral registers, a reconstruction of the hori-zontal and vertical extent of the cadastral proprieties which overlap each other on the little group of lots was possible, and the result was displayed by means of a three-dimensional digital model. By comparing the latter to the appearance of the city given by both previous scenographic maps and the reality of today, it is possible to state that the multi-storey structure of the Gregorian Cadastre of Bologna was not intended to describe the vertical extent of the buildings, but to experiment with a tool for raising taxes on urban buildings in a more precise way, by means of criteria which seem to anticipate the subsequent land register recording by real estate units. Unfortunately, the sophistication of such a system probably advised against its extension to other realities of the Papal State, making the Bo-logna experiment an isolate – even if for this reason more interesting – attempt.
