In 1917, second city engineer Arvid Södergren began work on producing a Historical Map of Gothenburg, depicting the development of the city from its foundation to 1923, when the city celebrated its 300th anniversary. The work includes a map showing the approximate appearance of the city's plots and parts of the buildings in the 1790s, making it the only representation of all the city's plots in the 18th century. Is it possible to produce a similar map of Gothenburg's plots and buildings in the early 18th century for the 400th anniversary of Gothenburg? The purpose of the following project is to visually reconstruct Gothenburg's plots and buildings in the early 18th century. Between 1717 and 1721, the first city engineer Johan Eberhard Carlberg produced about a hundred small plot and block maps of Gothenburg. The maps are fragmentary and difficult to interpret, but in combination with contemporary written and visual source materials can be used to compile a representation of the city's appearance in the early 18th century, based on empirical research. The results of the project create the conditions for conducting in-depth microhistorical research on cultural, economic and social variation in the city center of Gothenburg, with an innovative methodology that can contribute to the development of the city's history. The project will be presented in a book publication where the method for reconstructing the city's appearance is described in detail.
