"The Palace" told an obvious lie because they had to. Charles could not, for just a moment, remember where he was and why and be minimally polite.
More on-topic, sort of, back when Mrs. PeteS in CA celebrated our 20th anniversary with a trip to southern Germany, we did a Sunday visit to Dachau. The Nazi-era administration building has been re-purposed as a museum with exhibits. The former camp compound is bare, except for two full-sized replica barracks that illustrate the four major stages of the camp (during WW1 it was a factory worker camp; after WW2 it was a refugee camp; after being a refugee camp the facility was in such an awful condition that it was razed). At the opposite end of the camp, near the wall that circles the compound is a chapel. Outside of the wall is a crematorium. Outside of the camp wall is given over to trees, wildflowers, and grasses as a memorial to the many who died there whose ashes were scattered outside of the wall.
It's an extremely haunting place, knowing what evil went on there (and Dachau was for political prisoners, not a death camp like Auschwitz) and seeing the physical beauty that surrounds the camp. I would urge every American who could to visit a former concentration camp like Dachau or Auschwitz. Or like the Killing Fields in Cambodia, as one of my kids has.
