It is interesting to note that there is an unusually high number of underground wells. Several hundred have been found in a small area of the mediaeval town. As each house had several wells, it comes as little surprise that Pilsen’s burgers “grabbed” all the water resources. As a result, they had to build a water tower and water wheel. This pumped water from the functioning wells into the water tower, from where it travelled to the fountains on the main square. A replica of the original water wheel can be seen in the waterworks exhibit when you tour the Pilsen underground.
