Red staircase at Livrario Lello Porto

One of the most exquisite bookshops in the world, Livrario Lello in the Portuguese city of Porto is home to this lavish red staircase, making its interior as stunning as its incredible Art Nouveau and Gothic Revival facade. Lello is one of the oldest bookshops in Portugal and opened in 1901. While the staircase is its centrepiece, with carved wooden banisters and glossy red steps, the shop also features a marvellous stained glass ceiling and ornate wooden shelves holding books from every era and genre.
