Princess Diana’s tragic death in August 1997 was one of those truly world-stopping moments in our collective history.

She was just 36 years old.

The grief felt throughout the world was simply massive.

As her little brother, Earl Charles Spencer felt fiercely protective of Diana’s legacy and privacy.

In 1998, Spencer revealed some of the reasoning behind the spot.

A kind of destiny.

Whoever is in distress can call on me.

I will come running wherever they are."

In 2017 alone, there were four attempted break-ins (viaCloser Weekly).

“There are some odd people out there and keeping her right here is the safest place.”

Both princes are believed to regularly visit Diana’s grave when their schedules allow.

In 2001, Earl Charles Spencer was asked if Prince Charles ever visits the gravesite.

It’s an ex-wife at the end of the day and maybe that’s how he views it.

“Diana is a huge part of her boys' everyday life and always will be.

It was also significant because William proposed to Kate with Diana’s iconic sapphire engagement ring.

“It’s very special to me,” William told reporters during their engagement interview.

It’s unclear whether the trip happened, or whether Meghan had been there previously.
