If you like books (or if you don’t, it doesn’t matter), you should visit Lello & Irmão bookstore, located on Rua das Carmelitas 144. Opened in 1906, still runs and enchants visitors with its Art Nouveau and Gothic Revival interior. The spiral, wooden stairs in the center of the bookstore make a great impression. There is also a small café on the first floor. There is also one nice story about the library ;)
Picturesque ceilings and walls, reliefs or the big vitrage have a great impact on the atmosphere in the bookstore. Unfortunately, this can be ruined by tourists occupying every free space. They take photos of everything and it’s sometimes really hard to move. You can’t even use the stairs! I recommend visiting the bookstore right after the opening or before closing, otherwise you will left the place irritated. In August 2015 the entrance fee of 3€ was introduced and if you decide to buy a book, they will give you the money back for the ticket.
What made the Lello bookstore so popular, was probably J. K. Rowling, the author of Harry Potter books. She taught English in Porto and visited the place regularly, as she lived nearby. Is it true that the bookstore was an inspiration to describe magical Hogwart’s? Highly possible!
