There’s a castle in Scotland where the royals go during the summer.

Margaret Thatcher likened it to “purgatory” (viaThe Guardian).

As for Princess Diana?

(viaHarper’s Bazaar).

If you’re up-to-date on episodes ofThe Crown, you know which castle we’re talking about: Balmoral.

Think of a weekend spent at Balmoral like the royal equivalent of college sorority or fraternity hazing.

Princess Diana, Prince Charles, Balmoral Castle

You get the idea.

As it turns out,The Crown(with poetic license, naturally) got things mostly right.

Princess Diana, aristocracy herself, passed.

Although, unlike inThe Crown, Camilla may have had absolutely nothing to do with the occasion.

There’s a royal rule banning unmarried couples from the Queen’s residences, apparently.

How do you know if you’re in good graces?
