Mairi MacLennan, P7 Sgoil nan Loch and Hamish Scott, S1 Sir E Scott School, attended an awards ceremony at the House of Lords on Monday the 16th of May.
They had taken part in a poetry and art competition commemorating the First World War organised by the charity Never Such Innocence.
Mairi won first prize for art in her section and was awarded with a certificate and a £500 prize fund, half for herself and half for her school.
Hamish, who wrote a poem about Scapa Flow and the First World War, received a certificate and a special commendation, and he will attend the Royal Navy Battle of Jutland Commemorations in Edinburgh at the end of this month.
Both received a commemorative booklet with the art work and poems of all the winners and runners up from the 2015 -2016 competition from across Britain and the Commonwealth.
Comhairle Convener, Norman A MacDonald, said: “I would like to congratulate Mairi and Hamish on their recent success in the poetry and art competition commemorating the First World War.
"It is good to see our young people taking part in these competitions; the First World War is a constant reminder to us all as islanders of the sacrifices made by so many.”
Mairi and Hamish received a contribution towards their travel costs from Comunn na Gàidhlig and Comhairle nan Eilean Siar
