Bees living at Clarence House produce 40lbs of honey a year.
The residence of Prince Charles and his wife, Camilla, the Duchess of Cornwall, is open for summer visits this month, and the couple are encouraging guests to take in their impressive collection of 90,000 of the flying insects.
A series of posts on the official Clarence House Twitter account read: "If you visit Clarence House during the summer opening this month, you may spot these beehives in the Royal residence's garden!
"The Clarence House garden contains two beehives, which are home to over 90,000 bees. They produce around 40 pounds of honey a year. (sic)"
Charles is known to be a fan of bees as he also has some on his Duchy Home Farm estate, an organic farm which is part of the gardens at his Highgrove House country home in Tetbury, south west England.
Some of the honey those insects produce is sold in jars of Highgrove Home Farm Runny Honey on the shop's official website for £6.50 each.
The sales pitch reads: "Made in small quantities to traditional methods, this honey is presented in a rustic-style jar, finished with a Highgrove label.
"With an exquisite floral flavour, this honey is made by bees that forage pollen from around the estate hedgerows and orchards, and the surrounding countryside and gardens."
However, Charles, 68, hasn't always got on well with the yellow and black insects as he yelped in fright during an encounter with a bumble bee on his tour of New Zealand with Camilla in 2005.
Fortunately, he wasn't stung and after a few uncomfortable seconds the bee flew off.
