Architectural space elements created under water until 2020, by Lake Zakrzówek near Kraków

After around 80 years, when a SCUBA (Self Contained Underwater Breathing Apparatus) equipped human is able to explore the underwater world, it has turned out that there is a new area of creative possibilities. A huge number of people dive in different places. The most obvious are natural places such as seas or lakes. Among other directions of diving activity there are also disused open-air mines flooded with water. It is clear that there are not the same number of natural attractions. The management of the diving centre on Lake Zakrzówek, in order to increase the attractiveness of the site, carried out a number of underwater works. This is an old stone mine flooded with water. The maximum depth is 33 meters, but most of the architectural attractions are between 5 and 15 meters deep. The things placed there created an architectural space. Hundreds of divers have visited this place. The collection of architectural attractions was very diverse. Some things underwater were very original. There are simple structures such as: training platforms, shelters, mirrors, monuments, and some sunken things that are not architectural, such as an airplane, bus, car, and ship model. The study is a case study, describing how primitive construction activity can create an attractive underwater architectural space. Despite the very interesting natural shape of the lake bottom, the underwater architectural space was one of the greatest attractions of this place and a destination for diving trips. Presented work is the case study shows that the space built under the water in Zakrzówek was of great value as a document of the human creation in unusual conditions. Currently, the reconstruction of the border of Zakrzówek is underway. It is interesting if the architectural space will exist there, after.
