The Stockholm metro is often called the world’s longest art gallery thanks to its vibrant stations. 🚈 Also noteworthy but harder to spot are the small hidden ‘treasures’ both on stations and aboard the trains. 👀 Such as: – Unusually shaped ventilation grilles near the windows – 3D designs on the columns at the central station (T-Centralen) – Tiny figures woven into the seat upholstery Don’t miss them! 🤩 Music: Posing - Lofive / Epidemic Sound | Sweden.se
