  • (1878)

Not available in this edition

The official legal time in Portugal is established by this observatory, commissioned by King Pedro V, with a privileged location for astronomical observations. The need to accommodate very particular astronomy instruments gave this magnificent example of scientific architecture a strong technical character. Its design – by Jean Colson, accompanied by José da Costa Sequeira and Valentim José Corrêa – which is based on the Pulkovo Observatory, in Russia, is richer and benefits from the special surroundings of the Tapada da Ajuda urban setting. The scientific and historical importance, as well as the archives, collection, and library, is unparalleled in the country. The building is in situ heritage recognised as a Public Interest Property in 2022 and is part of the MUHNAC-UL since 2012.
