A holokauszt mártírjainak emlékműve - Budapest

In fact, there is very little information, written material on this monument, anyway I tried to scrape the Internet. It is known that it was designed by Alfred Hajós, an architect-Olympian, and was completed sometime in the 1950s. Is it before or after the 56 Revolution? I see a picture of a Fortepan from 1959, where a lot of people are standing around the memorial, presumably listening to a speech. The monument is large because on the one hand it consists of large stone slabs which also serve as pillars of the roof. There are many names on the stone slabs along with their year of birth. The names are grouped according to the locations where our compatriots are destroyed: in some places only the country like Russia, Germany, or "unknown place", in others the name of the camp is: Mauthausen, Bor, Birkenau, ... of course many names are still dwarfed by the total number of victims. I do not know how the names came up, at first I thought they were only Budapest, but not: there are people from other places (like Transcarpathia). The other part of the memorial is the large stone obelisk with the inscription: "Hate them, keep their memory with love". The same text is also in Hebrew. At the top of the obelisk is an amber, the green, the living, beautifully framing the stone. In front of it was a granite stone coffin that I could not find an inscription on. I assume that all victims can be a symbolic coffin. Many questions remain unanswered: at whose initiative was the monument erected, how Alfred Hajós won the commission, exactly when it was made, how long it was completed, when it was consecrated / inaugurated.
