I have visited the Majdanek camp, and I wrote about it on my website at http://www.scrapbookpages.com/Poland/Majdanek/index.html
This news article tells about the Majdanek concentration camp in Poland: https://www.wired.com/2017/04/vr-holocaust-history-preservation
The photo below is at the top of the news article.

This huge monument is very near a major highway which goes past the former Majdanek concentration camp.
The following quote is from the news article:
Pinchas Gutter has returned to Majdanek at least a dozen times, but this trip is his final one to the onetime Nazi concentration camp. His first was one he was 11, when he was taken to Majdanek; now he’s 85 years old, and this is the last time he’ll come here to tell people what the Nazis did to his family. As he rides up to the shuttered camp in the backseat of a chauffeured sedan, he talks about why he’s told his story so many times. Without that living, breathing reminder, the Holocaust becomes easy to forget—or even deny. Without personal accounts, Gutter says, it’s hard for people to accept its atrocities as “the gospel truth.”
Gutter is right about that. That’s why his trip to Majdanek, and the horrific experiences he recounts in the camp’s barracks and crematorium, are being preserved with virtual reality—thanks to the USC Shoah Foundation.
