Rua Academia das Ciências, 191249-122 Lisboa
The Academy was founded in the reign of Queen Mary I on the 24th of December 1779, during the Enlightenment under the name Royal Academy of Sciences. It is therefore one of the oldest national scientific institutions in continuous operation. In 1838, after changing location several times, it was finally moved to its current location by order of Queen Mary II in the old building of the Convent of Jesus of the Third Order. It possesses an important library resulting from the integration of the library of the old convent in its own spoils. Besides several important scientific works, it includes an old parchment of the early 12th century with a donation of Queen Mother Teresa to her son Afonso Henriques, the first Portuguese king.
