The series Vaults for Man exhibited by one of Spain's representatives Pablo Serrano at the 1962 Venice Biennale was a step forward in his reflections on humankind's reality in the contemporary world. For this series he created sculptures which "... are intended to be shelters for man, 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.
