Napoleonic Cadastre


The Napoleonic Cadastre was implemented between 1807 and 1816 and concerned the departments that had not been surveyed by the previous Teresian Cadastre.


For the survey phase, an implementation regulation is introduced with rules for measurements, sheet and section sizes, colourings and conventional symbols to be used.
As the unit of measurement, the metric system is adopted.


The maps are characterised by an accurate description of the area and by updated survey techniques. Sections made up of parts of the area delimitated by recognisable boundaries (usually the main streets and consolidated natural boundaries) are identified.
The area is divided into parcels, namely parts of land with recognizable and homogeneous boundaries in terms of property, intended use and quality.
The overall summaries (sommarioni) are organized into six columns and contain the sequential numbers, the names of the owners and of the locations, the quality, class and surface area of the individual parcels.
The maps of the Napoleonic Cadastre mark the beginning of a great process of territorial transformation.


  • tax equality in the geographical sense: between the kingdoms of the empire, between the different regions and between the municipalities within the same cantontax
  • equality in the social sense: no taxpayer may be exempted from paying taxes
  • geodetic framework of the entire territory of the empire
  • innovation in the agricultural sector: the tax envisaged was net of production innovations, thus favouring investment in the agriculture sector

The Napoleonic Cadastre after the Restoration

The Lombardo-Veneto territories, having once again been transferred under Austrian rule, were subject to new adjustments with regard to the cadastre.
In 1838 the new valuation rates were published and estimation of buildings began; in 1852, the new cadastre was activated which gave rise to numerous protests and objections.
In 1853, a technical commission was appointed, called Lombardo-Veneto Commission, which, as a result of estimates made on a sample of Lombard municipalities, confirmed the existence of a significant disparity in favour of the provinces in the Teresian Cadastre. It was decided, therefore, to carry out a new cadastral survey, that now known as the Lombardo-Veneto Cadastre.
