Comb of the Wind (Eduardo Chillida, 1976)

This guide to the Comb of the Wind in San Sebastian starts with a problem: sculptor Eduardo Chillida needed to lower three ten-ton steel claws onto this rocky point in the 1970s, and the US Embassy refused him the helicopter he wanted. You'll hear how engineer Jose Maria Elosegui solved it with a makeshift railed bridge for mining carts wheeled out over the tide, and how Chillida spent eleven years on the piece with architect Luis Pena Ganchegui, who shaped the terrace beneath it. Look at how the three claws are angled, two reaching toward each other and one facing the open sea.
