Mercat de Sant Antoni

• Sunday book market runs roughly 10am to 2pm, when ~100 stalls sell comics, stickers, trading cards, postcards, and old video games kids can dig through
• Climate-controlled food hall open Monday to Saturday, an easy mid-shopping stop with prepared-food and snack stalls
• Old city wall in the basement, the Sant Antoni bastion uncovered during the renovation, free to walk through on the -1 level

A restored 1882 iron market that fills a whole Eixample block under a 28-meter octagonal dome. Inside are fresh-food stalls, a ring of clothing and bric-a-brac stands, and a basement section of the old Sant Antoni city wall. Every Sunday morning around a hundred stalls take over the perimeter selling secondhand books, comics, stickers, trading cards, postcards, and vintage video games.
