A small Sunday morning antiques and collectables market that fills Plaza de Chamberí, the neighbourhood's main square, from around 9 am to 2 pm. Stalls are mostly run by private sellers rather than dealers — old prints, ceramics, silver, books, vintage clothing, and assorted curiosities. Not as large as El Rastro but considerably less crowded and more genuinely antique-focused.
Directly above the sealed Chamberí ghost metro station (the museum entrance is a few steps away), so the two can easily be combined on a Sunday morning. The square's café terraces are good for coffee before or after. Metro Iglesia.
