@gamieisonholiday: Hiding behind an unassuming bank facade in Paris lies one of the city's best architectural secrets. Inside the central branch of Société Générale on Boulevard Haussmann, you will find a breathtaking glass dome, intricate mosaic floors, and grand period architecture that rival the surrounding museums. (Make sure to head downstairs to see the massive, historic vault door too). The best part? It is completely free to walk in and admire during normal business hours. 📍 Société Générale (59 Boulevard Haussmann, 9th Arrond.) 💡Pro tip: Pair this with a visit to Galeries Lafayette nearby! Save this hidden gem for your Paris itinerary! • • #Paris #frencharchitecture #France #interiordesign
