The Queen is undoubtedly rich but there are 14 other aristocrats whose wealth, estates, and assets dwarfs hers.

The Queen is the 15th richest aristocrat in Britain and actually only the joint 319th wealthiest person in the UK – alongside music mogul Simon Cowell, according to the Sunday Times Rich List for 2016.

Her fortune is valued at £340 million ($418 million). She gets 15% of the profits from the Crown Estate property portfolio as well as an allowance derived from taxpayer money. She also has an extensive collection of valuable assets, such as art, jewellery, and cars.

But there are several aristocrats that have billions of more pounds than her.

Check out who made the list:

(All the ages of the people who made the list correspond to the time their fortunes were calculated, which was as of April 24, this year. Since the data was released, the Duke of Westminster died and so the information has been updated to reflect his heir's claim to his wealth):


14. The Duke of Northumberland
