A water square between Korzenna Street, Rajska Street and Wielkie Mlyny in Gdansk, which was designed by us, is to become an area with a strongly defined character, another point in the city’s tissue. A place filled with aroma and colour, with a unique genius loci.The design of the water square we propose does not attempt to compete with the surrounding architecture. Thanks to the horizontal form of the designed fountains, the monument of Johannes Hevelius still remains the dominant feature of this urban interior. On the square, which is not planar, we placed three fountains which are moon-shaped basins, and thus refer to the Moon as the main subject of Hevelius’ research. On each one’s arch there are ten geyser-type water nozzles which work independently of the water level and one steam nozzle in the centre. The fluctuation of the water level in the basins shows the power of the Moons gravity that is the phenomenon of tides. The changes in the water level in the central basin display the rising and the ebb tide on the Baltic Sea at a given moment (difference in the water level of about 14 cm). The basin towards Korzenna Street present the rising and the ebb tide in the Bay of Fundy. It is there that the greatest tides take place (water level
differences reach even 18 m). The basin towards Wielkie Mlyny Street displays the water level in Port Elizabeth. While there is low tide there, in the Bay of Fundy there is high tide. The designed water square is to be attractive not only for sightseeing tourists, but also for the local residents. It will be the only place in the vicinity where it will be possible to rest near water reservoirs. It is to be attractive at every time of the year. The fountains are designed for leisure; in summer it will be possible for children to bathe in them, and adults will be able to sunbathe on the shores of the basin. In winter, on the other hand, there will be three small ice rinks 13 metres in diameter. In early spring and in autumn it will be possible to create steam illuminations. The square is conceived to be a historical mark. It was divided into historical period.
