In addition to embellishing the urban space, the hanging colored umbrellas of the Umbrella Sky Projects protect public places from bad weather or, as in Castellar in the Alpes-Maritimes department, excessive sunshine. The alignment of dozens of umbrellas created by Portuguese artist Patricia Cunha indeed forms an original roof in the cities that welcome the performance. Under its shade, the inhabitants and visitors of Castellar can stroll on Place Georges Clémenceau and enjoy the market on Sunday morning.
