An ancient chapel has revealed a new mystery with the discovery of a 600-year-old hive built into the stones.

Builders renovating Rosslyn Chapel, which was made famous in The Da Vinci Code, found the "unprecedented" hive while dismantling a rooftop pinnacle.

The bees entered the hive through a hole in a carved flower crafted by the chapel's master stone masons.

The 15th Century Midlothian building is undergoing a £13m conservation and site improvement project.
