The Plaza del Rollo, located behind the Plaza de la Villa, in the heart of Habsburg Madrid, is home to this sculptural ensemble with which Madrid City Council pays tribute to the 449 Madrid Republicans deported after the end of the Spanish Civil War to Mauthausen and other Nazi concentration camps during the Second World War.

Unveiled on 2 March 2023, the monument consists of five pieces: a 5x5-metre gate, three 3-metre vertical structures and a support that includes the Mauthausen Oath, all of which are made of Corten steel by the sculptor José Miguel Utande.

The main sculpture symbolises the Gate of Freedom and expresses the shared dream that encourages those who built this memorial. Alongside it, there are three columns called The Trees of Dreams, symbolising the ordeal, on whose trunks the names of the 449 Madrid Republicans deported to Mauthausen and other concentration camps from 1940 onwards are written.

The ensemble is rounded off with the inscription of the commitment made by the survivors of the camps to tell the world what they experienced in order to prevent its repetition, known as the Mauthausen Oath.
