The master thesis outlines a design proposal for a new recreation center on the Adriatic Coast, in Nin, Zadar County. As a recreation center the aim is to ensure a perfect location for active and passive recreation using the town¿s most valuable natural potential, the medicinial mud (peloid). The effectiveness of the peloid has been tested and supervised by the Zadar Health Institution. This unique natural treatment can cure several diseases such as rheumatic diseases, spinal deformities, muscular and skeletal system problems, female infertility and various skin diseases. The project seeks to create a relaxing atmosphere for both local and visiting patients, just as people who would like to relax and recover surrounded by the nature.
