Santa Caterina or Isabel II Market was the first covered market in Barcelona. It was built from 1844 to 1848, the name coming from the original convent over whose ruins it was raised as it was customary then. Recently, the old building has been remodeled (1997-2005) by architects Enric Miralles and Benedetta Tagliabue (EMTB) those who designed the Scottish Parliament. Here is Santa Caterina Market as seen from the other side, notice the wooden structure that covers the ceiling and the metal beams that climb up like branches. The colorful roof (325.000 tiles) emulating vegetable and fruit stalls has become one of Barcelona's landmarks, although it can only be appreciated fully in official pictures or if you tip someone in the neighbouring buildings.
