Torre Glòries

This guide to Torre Glòries in Barcelona opens with the irreverent nickname locals gave French architect Jean Nouvel's bullet-curved tower over Poblenou, and the geyser image he insisted he was going for instead. It traces his nods to Gaudí's nearby Sagrada Família and to the jagged silhouette of Montserrat, then gets into the roughly forty thousand glass and aluminum panels and the gradient of color wrapped around the shell. Step back for the full curve of the tower before you decide which image fits it better.
