At one end of San Sebastián's La Concha ('Shell') bay is a set of 3 steel sculptures by the Basque sculptor Eduardo Chillida (1924-2002). The work is called El Peine del Viento ('Comb of the Wind') and was completed in 1976. Whatever you think of these pieces - which are full of tension - they do seem to fit well into the environment of this often stormy bay.
I found an interesting, subtle, gently curving, striated rock formation close by this monumental, aggressively thrusting, masculine sculptural work. A feminine contrast formed of natural stone? A bit of yin and yang going on here perhaps...
