I happened to stumble upon a lecture on YouTube: archaeologist Christina Rosén talks about the living conditions of the farmers who lived in the surrounding countryside, during the time when the City was being built.
Having gone to school in the City, I was well aware that it was built on clay. But it wasn’t until now, when Christina Rosén showed this particular image, that I fully grasped what it means to build a city-on clay.
What you are looking at, is a construction. It was designed to make it possible to build large and heavy structures on soft clay. What looks like stones, are actually the bottom of tree trunks. Whole trees, driven head first into the clay and then locked in place by the wooden grid you see in the photo.
Behind the staggering number of tree trunks that must have been used to build the City back then, you can sense a banal yet equally staggering manual labour effort. This came particularly from the farmers of the City’s surrounding countryside - and without using any machines. First, they felled the trees. Then, they stripped off the branches and bark. Next, they loaded them onto horse-drawn carts. Still, no machines. Then, they transported them into the city. Unloaded them again. And perhaps they also performed the process of pounding them into the earth and securing them with beams?
The farmers and their products were, in many ways, the concrete prerequisite for the city’s foundation on the stretch of land where it now stands. But, as Christina Rosén explains, their work was taxed as an extra levy. Ironically, this additional tax was called " Göteborgs-hjälpen" (The Gothenburg Aid).
Ironic, because at the same time, the City was actively working to attract foreign enterprising businessmen by offering them lower taxes.
The City rests on its opposite. There is a forest, standing upside down in the clay.
