Princess Estelle of Sweden is celebrating her 7th birthday this weekend!

The first child of Crown Princess Victoria and Prince Daniel, Estelle will one day rule the country of Sweden as Queen.

Just recently, Estelle and her mom got the chance to tour the Royal Treasury, which houses the royal family’s crown jewels.

Estelle peeped which crowns she would one day have a chance to wear and they include the Karl X Gustav, which dates to 1650, and Prince Oskar II’s pine crown from 1844.

A fun fact about the Swedish Royals: they rarely wear the crowns. Instead, they are often placed on pillows during important events to mark the significance of the occasion.
