One of the responsibilities for an architect is to provide a space that is usable and enhances the possibilities for what you do. But mostly, museums are just the opposite; they're horrible spaces, anti-art, they can't be used. They can't function, they overwhelm it. So in a way, they become objects in themselves many times, almost sculptures, and they get a lot of aggrandizement out of it...In terms of Bilbao, the one difference there is that they did not really want a museum, they wanted a monument. They wanted a thing that would bring people to the Bilbao.
To see with fresh, uninstructed eyes and an open mind requires a deliberate, self-aware act by the observer. Abstract artworks represent themselves and should be first viewed for themselves. When looking at outdoor abstract pieces, concentrate initially on the unique optical experience produced by the artworks. See as the artist saw when making the piece.
A focus on optical experience does not deny stories, it postpones them. Viewing an artwork may evoke interesting narratives – or just tedious artchat recalling similar art or artists, concocting playful tales, realizing how scrap metal was repurposed into art, making judgments about the artist's intentions or character, or contemplating an artwork's provenance, price, politics. Let the artwork stand on its own. Walk around fast and slow, be still, look and see from up down sideways close afar above below, enjoy the multiplicity of silhouettes shadows dapples clouds airspaces sun earth glowing. Your only language is vision.
