Dr Jones added: “I think Y Bwthyn Bach is a fossil, really. It’s historically interesting, you could argue that it is a part of Welsh history which might be better placed in a museum in Wales, like so many other relics of our past.”
Royal enthusiast Anne Daley, from Cardiff, hopes the cottage will continue to be used by younger members of the family rather than risk falling into disuse.
“It’s just another cottage that’s now empty – how many other are empty on that estate now?” she said.
“What about the Prince of Wales and Catherine? I wonder if their children would play in it. It’s only going to be forgotten about, dilapidated, unless Prince William lets his kids play there.”
If that were not the case, she too would like to see it return to Wales.
“It was a gift so it belongs to them,” she said. “I’m not sure really if you can ask for a gift back.
“But, historically, I’d love to see it, the public have never seen the inside.
“I would suggest bring it back to St Fagans museum and we can all have a look at it, even if you need to demolish it brick by brick and put it back together.”
