At their best his works, although massive and monumental, suggest movement and tension. For example, the largest of his works in the United States, De Musica is an 81-ton steel sculpture featuring two pillars with arms that reach out but do not touch. Much of Chillida's work is inspired by his Basque upbringing, and many of his sculptures' titles are in the Basque language Euskera. His steel sculpture De Música III was exhibited at the Yorkshire Sculpture Park in the UK, as part of a retrospective of Chillida's work.
Chillida's cast iron sculpture Topos V has been displayed in Plaça del Rei, Barcelona, since 1986.Chillida also conceived a distinguished oeuvre of etchings, lithographs and woodcuts since 1959, including illustrations for Jorge Guillen's Mas Alla (1973) and various other books.Wikipedia
