Market Rasen’s De Aston School marked its 150th anniversary year with a service in Lincoln Cathedral.
More than 1,000 pupils and staff filled the building, along with special invited guests, including many former pupils.
“De Aston is more than a school, it is a place to belong to; it gets under your skin and stays there,” said headteacher Ellenor Beighton in her welcoming address.
“De Aston School has gone through many phases, but the essence of the school and the sense of belonging in the heart of Market Rasen has stayed throughout.
“It is wonderful to have so many former staff and pupils here today.”
Prayers were led by six pupils - Adam Dame, Rhianna Melbourne, Jack Thompson, Poppy Smith, Head Boy Jordan Chilvers and Head Girl Emily Hancock.
Poppy spoke for them all when she said: “I feel honoured to have been chosen to represent the school and be part of its history.”
Musical items were performed by pupils Bradley Hanson on trumpet and Tek Hong Chung on violin, together with former pupil the well-known composer and conductor Patrick Hawes.
His brother the Rev Canon Andrew Hawes and fellow former student Canon Dr Peter Staves also participated in the service.
Chairman of governors the Rev Canon Alan Robson reminded pupils that they were just yards from the earthly remains of their founder Thomas De Aston.
“You are the heir to Thomas De Aston’s legacy,” he said.
After the service, it was back to school, where guests were able to view the display of archives and reminisce about their time at De Aston.
