Mercat de Collblanc, Art Deco marketplace in Collblanc, L'Hospitalet de Llobregat, Spain.

Mercat de Collblanc is an Art Deco marketplace with geometric decorations and symmetrical patterns adorning its facade. Large windows bring natural light to the interior spaces where permanent stalls sell fresh produce, meats, fish, and regional products.

Architect Ramon Puig i Gairalt completed this marketplace in 1932 during a period of architectural modernization in Catalonia. The building emerged when the city was updating its neighborhood infrastructure.

The market functions as a neighborhood gathering place where residents shop daily and interact with familiar vendors. It sustains traditional ways of buying fresh food that remain central to local life.

The building sits on a Latin-cross plan, so the two long arms are the main aisles and the shorter cross arm links them; the central nave rises above the side naves, giving two rows of windows. Indoor stalls open Monday 08:00–13:30, Tuesday to Thursday 08:00–14:00, Friday 08:00–20:00 and Saturday 08:00–15:00. Outdoor stalls keep different hours: Monday to Thursday 09:00–14:00, Friday 08:00–20:00 and Saturday 17:00–20:00.

The market stands on the plot where Collblanc's weekly open-air market was held before the building went up in 1932. The 1925 land purchase by the town council and the 1926 expansion plan by municipal architect Ramon Puig i Gairalt turned that informal fairground into a covered hall.
