This one is only a 12 minute walk from the more famous Mercat de La Boqueria on Las Ramblas, yet it is a world away in terms of experience.
Much smaller, but a much more spacious set up internally with all the same type of food stalls you can see in the more famous one, it is considerably less busy and lower cost. It also has the associated cafes and bars around its periphery but because of the extra space to the back of the market the bars and restaurants here have outside sections on the pavement also.
The funky modern roof design gives the market character and this spacious, modern market building was constructed on the former site of the Convent of Santa Caterina, from which it takes its name and there is an exhibit showing some historic ruins of the convent and information boards providing the background and history of the site at the main southern entrance to the market.
