Sant Antoni Marketplace, Cast-iron marketplace in Sant Antoni, Barcelona, Spain.
Sant Antoni Marketplace is a cast-iron market hall in the Sant Antoni neighborhood of Barcelona. The building extends across an entire city block with four diagonal wings that meet beneath a central octagonal dome made of metal and glass.
The market hall opened in 1882 during the urban expansion of Barcelona and was among the first commercial buildings erected outside the medieval walls. Its construction marked the shift from the old walled city center to the planned modern districts of the nineteenth century.
The Sunday flea market section attracts collectors and readers with its selection of old books, comics, stamps, and trading cards. Visitors often spend hours browsing the stalls in search of rare editions and forgotten treasures from Catalonia.
The food section operates Monday through Saturday between 8 AM and 8 PM, while clothing stalls open daily except Tuesdays and Sundays. Access is available through multiple entrances on each side of the building, making it easy for visitors to find their way in.
Archaeological excavations beneath the building uncovered medieval fortification remains and a sewerage system from Roman times, now visible in the basement area. The findings show the different layers of urban development at this location over two millennia.
