Unesco World Heritage status is a rarity for an industrial building, but this 'glass palace', a former coffee, tea and tobacco factory built between 1925 and 1931, is a 20th-century icon. It's now filled with design studios and is closed to the public but Urban Guides runs 75-minute tours (adult/child €12.50/7.50) at 10.30am Wednesday to Sunday July and August, and 10.30am Saturday and Sunday in May, June, September and October.
