Royston Cave will once again be opened for a special Christmas candlelight display on Saturday.

The Melbourn Street landmark will be open between 10.30am and 1pm, and costs £2.50 for adults and 50p for children.

You don’t need to book in advance – just turn up on the day and pay the guide at the door.

The age of Royston cave, a man-made cavern in the shape of a beehive, is still a mystery.

It is known for its extensive wall carvings of saints such as St Katherine, St Laurence and St Christopher. Other figures have been interpreted as pagan symbols.
