A sloping public space designed by Chillida and Peña Ganchegui in the early 1980s as a piece of urban sculpture. The pink stone slabs step down in shallow terraces around a small fronton (Basque pelota court); a fountain and a small underground exhibition space complete the composition.
It is one of the more interesting pieces of late 20th-century public design in northern Spain — abstract, severe, and resolutely Basque. Locals use it as a meeting point and as the slope for a quick game of pelota.
