In 1960, on the occasion of the commemoration of 500 years since the death of Henry the Navigator, the monument was reconstructed in concrete and rose-tinted Leiria stone, with sculptures made of Sintra limestone masonry.
The project, designed by Cottinelli Telmo, was then carried out under the guidance of António Pardal Monteiro. Stability studies were conducted by the engineers Edgar Cardoso, Ruy Correia and António Abreu. Work on the interior was implemented by António Pardal Monteiro, while the surrounding area was laid out by the architect Cristino da Silva.
The sculptures were modelled by Leopoldo de Almeida, with the help of the sculptors Soares Branco and António Santos.
Inauguration on 9 August 1960
