Lello Bookshop is certainly one of the most beautiful in the world. It has a particular and unique architectural style, which combines all three: neo-gothic with art nouveau and art deco styles. It was designed by the architect Xavier Esteves and inaugurated in 1906. An incredible art nouveau staircase and wooden walls make this bookstore exquisite as it can be. Rumor says that Lello bookshop also inspired J.K. Rowling to write Harry Potter, after its 2 years living in Porto during the 90s. There are indeed some similarities between this bookstore staircase and the Hogwarts library. Lello’s Bookshop is located right beside Torre dos Clérigos and has an extraordinary value. Historical and architectural.
