Mercat de Santa Caterina
Viewed from the sky, the undulating roof of the Santa Caterina Market with its flamboyant hexagonal mosaic tiles reflects the treasures contained within it: fresh fruit, veg, meat, fish and other delights. The current iteration was designed in 1997 by architects Enric Miralles and Benedetta Tagliabue, while the roof by artist Toni Comella was a colorful addition to what was then a run-down food market originally built in 1845 to serve the neighborhood's blue-collar workers. Unlike the fabled La Boquería in La Rambla, this is a place where locals still go for their daily produce, even though its setting in one of the most tourist-heavy parts of city means many of the stall-keepers are also accustomed to conversing in English. While you're here, stock up on extra virgin olive oil from Olisoliva or try some Iberian jamón (ham) from Xarcuteria Carles, a local favorite.
