A pair of old wooden lock gates removed from the Bridgwater and Taunton Canal are being used at this year's Glastonbury Festival.
British Waterways said the 200 tonne (440,900lb) gates had come to the end of their working life.
Glastonbury founder Michael Eavis said a use will be found for the gates.
Last year, canal gates were used at the festival to build a bridge in memory of Arabella Churchill, who helped organise the first Glastonbury Festival.
Sarah Rudy, from British Waterways, said: "Just because we no longer have a need for them on the waterway, doesn't mean that nobody else can make a use for them.
"It's brilliant that the festival team have found an inventive and pretty unique way to put them to another good use."
She added that the black and white beams which people see above the water-line were being donated to the Maunsel Lock Canal Centre, Bridgwater, where they will be turned into raised flower beds and extra seating.
Michael Eavis, Glastonbury Festival founder, said: "It's great that British Waterways has donated these wonderful lock gates to us, and even better that they have come from the local area.
"From beautiful bridges to sound proofing our noisiest circus arena and lots more ideas still to come, I guarantee these gates will not be wasted."
The 14.5 miles (23.4km) Bridgwater and Taunton Canal opened in 1827 and links the River Tone to the River Parrett.
