More than 1,000 sandcastles - hopefully - will pop up on Scarborough's South Beach today as part of a Guinness World Record attempt.
The attempt is part of a "Coast to Boast About" initiative which aims to make Yorkshire's beaches the best in Europe.
To qualify, there must be more than 1000 sandcastles, measuring two foot high and two foot wide, with a turret on top. They must be built within an hour - and remain standing for another hour.
The attempt will take place at 11 am.
Steve Pace, from Yorkshire Water, which is behind the idea, said: "We are investing £110 million along the Yorkshire Coast to help break records with our bathing waters. This 'Coast to Boast About' event is about giving our customers the chance to be part of their very own record-breaking attempt, whilst also enabling them to come down to the beach to find out more about the work we, and our partners are doing."
Andrew Williams, Scarborough Borough Council Leisure Manager added: "The record breaking attempt is about being the best and achieving the highest standards possible. This mirrors the aim of the Yorkshire Bathing Water Partnership, which is to strive for the best bathing waters in Europe and have a 'coast to boast about'. I encourage local residents and visitors to Scarborough to join us in our record-breaking attempt and play their part in highlighting all that is great about the Yorkshire coast."
