Back in the 1990s, De Biesbosch, a nature sanctuary in southern Holland, was named a national­ park; from the start it had an 11-part visitor centre. The pro­gram to safeguard the country against flooding included educational measures such as this museum.

The architects decided to retain the pavilions and add a wing holding a restaurant and temporary exhibitions. They refurbished the existing structures and covered the entire complex in a ­layer of vegetation.
