The oldest bookshop in the world is located in Lisbon - or at least the place where there has been sold books from the same adress for the longest time. It all started in 1732, more than twenty years before the devastating earthquake which wiped out the lower parts of the city.
Today it is part of ‘Bertrand‘, a chain of bookshops, and though it is a beautiful shop it doesn‘t look THAT old. I bought the tagged book which I look forward to.
