May Day (1 May) 1962 was one of the largest demonstrations against the dictatorship, bringing workers’ and students’ mobilisation together, in the middle of the academic crisis. The demonstrators gathered at various points in the city, and there were clashes in the Terreiro do Paço, the Carmo, the Rossio, Martim Moniz and Alcântara.

Around Rua da Madalena and Largo do Caldas, demonstrators and police forces clashed, and the police fired bursts of machine-gun fire. Estêvão José Dangues Giro, a typographer from Alcochete, who is said to have had links to the PCP, was fatally hit. He was 25.

As the Aljube Museum points out, the killing took place “very close to the Aljube”, the PIDE’s political prison, and a few days after two miners had been killed in Aljustrel, at the end of April.

The repression combined the riot police, the GNR, the PIDE and the Portuguese Legion, and only late into the night did the authorities manage to regain control of the Baixa.

    Salgueiro Maia’s column climbed this street, from the Rossio to Largo do Carmo. It was here, at the start of the street, that Celeste Caeiro gave a carnation to a soldier who asked her for a cigarette — and the carnation became the symbol of the revolution.
