A university student from Guernsey who has been working with a team of archaeologists excavating an 8th Century monastery has said it has been a great experience.
He was part of a team from the University of Reading digging up an Anglo-Saxon site next to Holy Trinity Church in Cookham, Berkshire, in England.
Mr Charmley, who was left visually impaired following a brain tumour, said it was "mind-blowing" the work had helped find evidence that the Cookham monastery was a social and religious hub.
He added he also had the chance to help his colleagues understand more about visual impairments.
Mr Charmley was diagnosed with a brain tumour after a routine optician appointment in April 2021.
He underwent six weeks of radiotherapy and two operations during treatment for the tumour.
But, during the second surgery, he experienced nerve damage and lost the sight in his right eye.
However, he told BBC Radio Guernsey it had not held him back in his "hands-on" archaeology course, including the dig, which began in August and finished on Sunday.
Mr Charmley said: "I've always been interested in history and and the objects left behind and particularly interested in the history of ordinary people."
He said his disability had had "some impact" when digging, but added: "I may not be able to see small changes in soil colour which indicate things, but I can hear and feel difference when trowelling."
He added: "Discovery can be best described with a fishing analogy.
"You can spend hours and hours trowelling away, but the moment you get that find, it is the best feeling in the world.
"To be the first person to see and hold that find in 1,200 years, it's just mind-blowing."
The university plans to return to the site next year for what will be its third dig there.
