A must-visit for book lovers, the Libreria Acqua Alta translates into "The Bookshop of High Water" and is found in a city that sees constant floods. The waterways are known to rise, filling up the shops with inches of water, and as the books are highly prone to water damage, the store has found creative ways to combat the issue – by storing their copies in bathtubs, waterproof containers, and even a full-sized gondola. Books are stacked wall to wall in this whimsical shop and is definitely one of the most interesting bookshops in the world.
