One Sunday I took a walk over the river to Benimaclet to see the ‘Cases de Trencadis’ which translates badly as ‘The Tiled Houses’. Actually Trencadis refers to a type of mosaic made of broken pieces of ceramic tile. This technique was used by Catalan modernism architects, most famously by Gaudi and Jujol in Parc Guell in Barcelona.
These houses were built in the 1930s by Jose Sanmartin Zarzo, an uneducated bricklayer with no formal training in architecture, in tribute to Gaudi.
Zarzo collected leftover tiles from the building sites he worked on to create the façades. The corner building is now a fruit and veg shop but it was closed on the day I went.
