The monument was erected on an isolated clifftop 133 m above the sea, overlooking the Tagus River left bank. It was constructed in the parish of Pragal, which was merged with the parishes of Almada, Cova da Piedade, Pragal e Cacilhas in 2013, into the municipality of Almada. It is the highest point in Almada, on a plateau dominated by the 25 de Abril Bridge, and close to the Estação Elevatória e Reservatório do Pragal. It is accessible from Lisbon by car (over the 25 de Abril Bridge east of the crossing), by train through station in Pragal and by ferry (the "Cacilheiro") over the Tagus, through the port of Cacilhas in Almada.
