The Duchy of Lancaster is a private estate owned by Her Majesty, and this portfolio not only includes 8,481 hectares of land in England and Wales and these epic castle ruins, it also covers urban properties. The Queen owns things like Wellington House in London and The Harrogate Estate up north which includes a care home, hotel and a school.
So, basically, no matter where you are in England, it is likely that you are close to something owned by the Queen – and not forgetting the swans, of course!

The monarch may own an array of properties, but what may surprise you is that she does not own her most famous residence, Buckingham Palace.
The 775-room royal residence, in fact, belongs to the Crown Estate, and not the Queen herself.

The Crown Estate website explains: "The Crown Estate belongs to the reigning monarch 'in right of The Crown', that is, it is owned by the monarch for the duration of their reign, by virtue of their accession to the throne. But it is not the private property of the monarch - it cannot be sold by the monarch, nor do revenues from it belong to the monarch."
