Pupils from West End Primary School in Bedlington joined hundreds of other youngsters in the north east Sandcastle Challenge.
And they were joined by construction specialist Galliford Try who worked with Year 3 pupils and teaching staff to create the four apostles in sand on Sandhaven beach in South Shields in an event organised by children’s charity Children North East.
The challenge was to construct Lindisfarne Gospel themed creations with a winner being selected by a team of 25 judges.
Jonathan Smith, a teacher at the school, said: “Being involved in the Sandcastle Challenge provides the children with a fantastic opportunity to work closely with a partner company on a big project.
“The children loved meeting members of the Galliford Try team and were able to discover the huge range of opportunities available in the construction industry.
“The children were delighted to be chosen as one of the winning teams as they had worked incredibly hard in the classroom on their designs and they learned a lot about the Lindisfarne Gospels in the process.
Debra Phillips, HR advisor at Galliford Try Partnerships North, added: “It was great to be involved in this year’s Sandcastle Challenge and we are delighted that the children had such a good day at the beach.”
