Students at West Oaks Specialist School and College saw the start of their sculpture trail begin to take shape.
The Boston Spa-based pupils recently unveiled the first part of the trail designed to depict aspects of the outdoors including insects and plants.
Pupils in Swift class, teacher Fiona Burns, and staff Shirley Harrison and Sarah Webster worked alongside sculptor Alan Pergusey to create the sculpture.
A spokesman said: “Pupils worked hard on drawings to then develop their designs.
“Each then made detailed mosaic panels to fit together onto the sculpture.
“The result is a vibrant and beautiful representation in a rainbow of colours.
“The sculpture is designed to walk in and around and to be sat on and touched.”
Parents, carers and pupils from the school attended a special unveiling in the grounds of the school and were delighted with the result.
“It made me feel happy and proud when it was completed.” said Swift class pupil Ria.
Teacher Fiona Burns added: “It was rewarding to see the pupils concentrating and being so focussed on the task.”
