When Nivo PLC, a construction and water company based in Celje, undertook a project to rehabilitate a plot of degraded land south of Žalec near Vrbje in 2003 something strange happened. Workers on the site began experience strange energetic sensations radiating from the land, which seemed to have beneficial effects on their physical health and psyche. Experts from the field of bioenergetics were called in to take measurements with specialised equipments, and it was concluded that the area possessed a special natural energy field that could be harnessed in advantageous ways. Nivo decided to build a park on the site, and open it to the public (for a small admission fee). There are now two artificial lakes and a long walking path circulating around the property. Colour-coded rocks have been set at various points of especially strong energy, each corresponding to a different organ or part of the body. If you visit, keep an eye out for one of the white swans who seems to be at least slightly evil, and will aggressively follow you around the pond (or perhaps he just didn't like us!).
