Meghan Markle and Prince Harry are expecting their first child together, and they place where the baby was conceived has just been revealed.

Adam Helliker, a journalist for Express, claimed that the Duke and Duchess of Sussex conceived their baby at the Castle of Mey in Caithness. The royal couple joined Prince Charles at the royal castle last summer, and they were there for five days.

“They stayed there for five days and, even though they went for long walks during the day, nobody bothered them and they were very self-contained. They spent a lot of time in their room, so we think it’s where it happened,” he said.

The Castle of Mey was a residence of the Queen Mother. When she was still alive, Queen Mother would spend three weeks in the castle every August and about 10 days in October.

In related news, Kensington Palace announced that Markle and Prince Harry are expecting their first child together last week. The couple will welcome their baby sometime in the spring of 2019. One the same day, Prince Harry and Markle kicked off their overseas tour of Australia.

During their recent engagement in the continent, Markle was photographed touching her baby bump while walking on Fraser Island with her husband. Since they arrived, Markle has already missed three engagements that she was supposed to attend if she wasn’t pregnant.

A royal aide issued a statement regarding Markle’s state and clarified that the “Suits” alum isn’t sick.

“She isn’t sick, she just had a tiring few days and we were concerned about the roads on the island which are incredibly bumpy and uncomfortable for anyone, let alone a pregnant woman. But the Duchess was very keen to re-join the duke at the last engagement of the day to greet the people of the island,” the source said.

Prince Harry and Markle will also visit New Zealand, Fiji, and the Kingdom of Tonga before their royal tour wraps up on Oct. 31.
