>>63889941I'm Swedish and one of my classmates was part of an old noble family.
One time he invited the whole class to his family's "castle", more of a really big mansion really, and all of the walls were covered from floor to ceiling with stuff that you would think are supposed to be in a museum.
Centuries old swords, pistols, muskets, maps, flags, armour, war loot etc.
Even the history teacher was shocked and asked his father if these things weren't better kept in a museum and the father just said "they are ours".
Apparently a huge amount of European history and artifacts are kept in private hands.
