Abstract

Inaugurated in 1965, the Calouste Gulbenkian Planetarium (CGP) was the first institution of its kind in Portugal. The CGP was established in the context of the relocation of the Maritime Museum of Lisbon (Museu de Marinha) to Belém, an area of the Portuguese capital highly symbolic of Portuguese maritime and imperial history. The dictatorial regime known as Estado Novo used Belém as a ground for major events that affirmed the legitimacy of Portugal’s overseas empire by celebrating the maritime deeds of erstwhile sovereigns and navigators, in a mythical narrative of a glorious imperial destiny. Given the close association between astronomy and nautical science, the CGP was certain to gain a prominent place in the tapestry of Belém’s symbolic inscriptions. This paper addresses the inception of the CGP in its urban context, showing how this area of Lisbon provided an ideal backdrop for this institution, and how its foundation was promoted and steered by a naval officer and amateur astronomer who maintained an ambivalent relation with the regime: Eugénio da Conceição Silva (1903–69).
