Agueda in Portugal is the setting for this wonderful installation by Sextafeira called Floating Umbrellas. This colorful creation is a part of the Agitagueda art festival. Due to the fact that the same idea was used last year this is the second time the streets of this town have been covered with loads of vivid umbrellas, providing shade, as well as a wonderful sight. The people loved it so much that the repetitive nature of the installation does not carry the risk of becoming boring, but rather turning into a wonderful tradition.
