Gaudi's Sagrada Familia Cathedral and FRP

Gaudi’s Sagrada Familia Cathedral and FRP

This iconic cathedral in Barcelona has been under construction since 1883, and it is looking like years before it will be finished. The beautiful concrete columns and interior details are being formed with the help of fiberglass molds, cast in place several stories in the air.
