One of the things Lisbonites like to do on Saturdays is go to Chiado, look at the shop windows, go shopping and cross Rua da Anchieta to buy a rare or second-hand book calmly exhibited on the booksellers’ stalls all day long. From 10 am to 5 pm, a bit of Portuguese history can be found here, from comic books to recent releases, illustrated postcards and special editions. Covering various genres and eras, the calm and unpretentious atmosphere ensures a large flux of people. When it rains, improvised waterproof covers are thrown over the stalls, and the low prices, combined with the location, guarantee a few well-spent hours. Take the chance to buy a book to spend the next hour in a pavement café watching the time and people pass by at the best human observatory in Lisbon: Chiado.
