A group of musicians are claiming the world record for the highest number of harps played at the same time.
The harpists prepare for their world record attempt
The 45 harpists, who are touring north Wales, performed a concert in the 13th Century Denbigh Castle.
They plan to contact Guinness to see if their efforts qualify for a record.
One, Harriet Earis said: "If nothing else, it's been great fun, and we're now very confident we'll make it into the record books."
Musicians from the Flintshire County Harp Ensemble were joined by harpists from Ceredigion and members of the Surrey-based International Harp Ensemble for the attempt.
The musicians - aged between five and 55 - are coming to the end of a tour of west and north Wales.
Ms Earis said: "To be honest, we don't know if there is a record - we doubt anyone has ever been mad enough to try it.
"But I'm fairly sure it will qualify as a world record. The next step is to contact Guinness."
It is thought Denbigh castle site was originally the stronghold of Dafydd ap Gruffydd, the brother of Llywelyn, Prince of Wales.
But in 1282 the fortress fell to the English and the town was given to Henry de Lacy, Earl of Lincoln.
