The series Vaults for Man (Bóvedas Para el Hombre) in which Pablo Serrano exhibited at the 1962 Venice Biennale while representing Spain is a step forward in his reflections on the reality of humanity in the contemporary world. For this series he created sculptures that "... are intended to be 'shelters for people,' even though the vaults are in ruins ..." He sculpted concave volumes made from a mixture of plaster, cement, wooden slats, bricks, and other materials which gave rise to compositions which the sculptor later turned to bronze, giving form to those imperfectly elaborated refuges to embrace a changing society which continued to reconstruct itself after the conflicts of war which characterized the 20th century.
