One of the major industries of Catalonia is fishing. This is a traditional Mediterranean Nansa Fish Trap. The technique of making these woven baskets is used by various artisans to make a huge variety of baskets and traps. Quoting from the website, TimJohnsonArtist.com,
In Catalonia ‘Nansa’ fishtraps were made in a variety of shapes and sizes depending on the kind of fish they wanted to catch, the traps were usually made in the winter with a very tough kind of rush (Juncus acutus) as well as split cane (Arundo donax) and olive stems.This is quite a large trap that I photographed at the Smithsonian Folklife Festival 2018 in Washington, D.C. at the Mall. It was part of the emphasis on Catalonia crafts and artists.
