The secret to this bookstore’s historical wealth lies in its enduring presence over time: not only limited to selling books, it has also hosted illustrious figures from Portuguese history, thought, and literature. It has witnessed events such as the 1755 Lisbon earthquake, a civil war, a regicide, the establishment of the Portuguese Republic, the unification of Europe, and many others.
Frequented by prominent figures of Portuguese literature, such as Bocage, José Agostinho Macedo, and Curvo Semedo, it was also a gathering place for literary salons by writers from the Generation of '70, including Alexandre Herculano, Eça de Queiroz, and Ramalho Ortigão.
Bertrand Chiado holds stories that have shaped it over its 285 years. One example is the story of José Fontana, a former bookseller and one of the managers who passed through this establishment. The founder of the Fraternity Workers Association, when already suffering from tuberculosis, tragically took his own life in what was then the bookstore's storeroom, now the Café Bertrand.
