Designer Maria Pinho of Sexta Feira works to install the Umbrella Sky Project Tuesday outside Gateway Center in Downtown Pittsburgh. About 300 umbrellas were installed and will remain hanging during the Three Rivers Arts Festival. The project began in Agueda, Portugal, as a way to create shade and keep people cool during the summer, says Alexandra Guedes, a designer with the Umbrella Sky Project . "It's an unusual way to bring color to the people." (Rebecca Droke/Post-Gazette) #Pittsburgh #PGH #412 #GatewayCenter #ArtsFestival #ThreeRiversArtsFestival #umbrellas #art #PGPhotos
