They wanted a monument
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.
Gifts and occupations
Between 1835 and 1850 Froebel worked on his “Gifts and Occupations” — a set of geometric blocks (Gifts) and basic craft activities (Occupations), that would become the centerpiece of his pedagogical theory. The Gifts and Occupations were introduced in a highly ordered sequence, which began in the child’s second month and concluded in the last year of kindergarten.
