Opened in 1906, Livraria Lello is one "ex-libris" in Porto and it was considered by The Guardian journal the third most beautiful bookstore in the world.

Designed by Xavier Esteves, the bookstore's architecture and interior design are stunning. The facade is an excellent neo-gothic design. Once inside, there is the curvaceous red stairway connecting the two levels (inspired on the Parisian Galleries Lafayette), the heavily decorated walls and ceilings, and the magnificent stained-glass skylight with Lello’s motto "Decus in Labore" will no doubt impress you.

The pillars are ornamented with bronze bas-reliefs of Portuguese literature figures and there is a small track on the floor along which employees move carts filled with books. All in all, Lello is one of the best works of the so-called “second eclecticism” style in Portugal, with beautiful art nouveau naturalist elements.
