SCHOOL children have planted a time capsule to mark the 50th anniversary of the opening of a steel mill.

Tata Steel is celebrating 50 years of processing from its 20-inch Hartlepool mill.

To mark the occasion, bosses invited school children from Barnard Grove Primary School, in Hartlepool, to bury a time capsule in land outside the 20-inch mill.

Alexander Bradley, Jazmyn Williamson, Evie Blair - all 10-years-old, and nine-year-old Jay French all got the honour of planting the historic capsule.

The pupils then released some balloons to mark the occasion.

Andrew Ward, works manager at the 20-inch mill, said it was a "fantastic" day and credited the people who had worked on the site over the last five decades, which at one point reached 5,000.

Tata have processed steel for projects all over the world, including the Louvre in Abu Dhabi, the London Eye, HMS Queen Elizabeth, the expansion of Liverpool's Anfield Stadium, Swansea City's Liberty Stadium, as well as football stadiums in South Africa and Cameroon.
