Doctor António Nunes de Carvalho, man dedicated to the memory, played an important role in the enhancement of national heritage. Liberal, academic, former political exile, he served in charge of Deposit of Libraries of Extinct Convents, when he defended the conservation of Arrábida, place with history and unique features. We propose to reveal more about a personality with important contacts and an interventive action in the society of that time, as part of the liberal and romantic currents that contributed to the implementation of heritage policies during the first half of the 19th century.
