I could not find any additional information about this monument but as you can see it is for all those who were persecuted during World War II including gays, gypsies, disabled people. As you can see it’s very much part of the daily landscape of this neighborhood in Rome. In the background is the Pyramid of Caius Cestius who died in 12 BCE and had himself buried in this pyramid. It’s 89 ft. tall and under renovation. Delusions of grandeur?!
