More than just a bookstore, Livraria Lello is a historical and architectural masterpiece in downtown Porto. Opened in 1906, Livraria Lello & Irmão as it is also known combines elements of Neo-Gothic, Art Deco, and Art Nouveau styles that comprise intricate woodwork, a large stained glass window bearing the bookshop monogram with the motto "Decus in labore" (dignity at work, in Latin), and a remarkable red spiral staircase, which starts as one set of stairs and splits into two that join in a circular design. The latter is a huge attraction here since it resembles the Grand Staircase from the Harry Potter films, and considering J.K. Rowling was once a Porto resident, there is a high chance this place might have inspired her. Livraria Lello became so popular with tourists that in July 2015 the store started charging a 5 Euro entrance fee and queues can take over an hour. You can purchase tickets on their website.
