Historical overview map of the city of Zurich around 1859-1867 (old city cadastre)

Real estate catastrophe plans with the insurance numbers from 1859-1867 of the then municipal area of the city of Zurich. The 1:200 scale plan plant consists of 246 sub-sheets. One sheet covers an area of 120 m x 90 m. Was drawn with ink and watercolor colors on cardboard. In addition to the building outline, many other structural elements of the city are shown (see below). The scope of the buildings was taken up at ground floor level. Fronts and backs on the facades are taken into account, but not windows and doors. On the other hand, the fire walls and the exact course of the house boundary in their area are shown. With a red line, residential buildings or fixed buildings (churches, monasteries, mills, factories and school and hospital buildings, etc.) are distinguished from ancillary or commercial buildings (orange accompanying line). Also marked in red is the cutting surface of vertical components such as walls, pillars, columns and support woods. In addition to the insurance numbers, the house names (if available) serve to identify the building. Street names complete the inscription. Individual elements are reproduced in the supervision in a naturalistic manner: low walls, stone slabs, stairs, fences, hedges, embankments, garden rebates, wooden bars, streams, fountains, street lanterns, and more. Individual trees, on the other hand, are recorded schematically but correctly with stem and indicated crown. Different colours (blue, light green, grey, brown, etc.) are used to identify the soil cover of large areas (water, meadowland, paths, paved places etc.). Hidden structures (channels, underground spaces, river banks under bridges, bridge piers, etc.) are also shown (dotted lines). The boxes are dated and signed by the draftsman. **Purpose**: — Historical data source for the built city with all the individual elements for the period around 1860. — Usable to determine the structural changes compared to today’s city. — Source of information in the planning and conduct of archaeological investigations.
