Sweden's royal residence is haunted, according to the country's Queen. 

Queen Silvia made the startling claim in a documentary which is set to air on Swedish public television station SVT this week.

Sweden's longest-serving queen told the documentary makers Drottningholm Palace, which dates back to the 16th century, is also home to some ghosts, BBC reports.

But instead of being a sinister presence, 73-year-old Queen Silvia says they're friendly.

"It's really exciting. But you don't get scared," she says. "You sometimes feel that you're not completely alone."

The palace is the private residence of the current royal family - Queen Silvia and King Carl XVI Gustaf - who have lived there since 1980.

The King's sister, Princess Christina, has also experienced the "energy" in the palace.

"It would be strange if it didn't take the form of guises," she says.

The original palace was destroyed by fire in 1661, with work beginning on the current building the following year.

Drottningholm, which literally translates to Queen's Island, is a popular tourist attraction. Parts of it, including reception halls, are open to visitors year-round.
