Also known as Andén 0 (Platform 0), this is an intriguing opportunity
to visit the ghost Metro station of Chamberí. Built in 1919 and abandoned since 1966, the old station has been
completely restored and you can again walk its ticket halls and platforms and admire the ceramic signage, old
advertisements, and vintage fittings. A treat for transport buffs and children, it’s also a beautiful exhibition of early
20th-century commercial art.
