The Sunday City was born from an idea by the industrialist Mario Spagnoli of Perugia (1900-1977), who in 1955 bought 100 acres of unproductive land on Monte Pulito and planted an olive grove. In 1960 he decided to transform the mountaintop (altitude of 600 meters), into a leisure park designed especially for families. He personally oversaw all of the works, which were carried out by technicians, artists and craftsmen.
Opened in 1963, this was the first example of this kind of park in Italy. Two stone pillars (the “Kessler”) were raised to mark the main entry into this fun park. From the start the park was characterized by the inspiration of fairy tales, but each year improved by new attractions.
