Supporters of a former North Yorkshire mill are hoping it will win the final of the BBC's Restoration series.
Gayle Mill won the regional restoration final
Gayle Mill near Hawes is one of eight finalists with the winner being decided by a telephone poll of viewers.
The mill was built in 1776 and made cotton and wool before becoming a sawmill. It closed in the 1980s.
If they are successful, the Friends of Gayle Mill will use the money to restore it to produce timber products and create a visitor centre.
Their aim is to "revive sustainable craftsmanship, providing employment and training in traditional skills as part of the rural economy, inspired by the historic setting".
The building has been designated a Scheduled Ancient Monument and a turbine which replaced the waterwheel in 1879 is thought to be the the oldest working turbine of its kind.
In a regional final it fought off competition from Manor Lodge in South Yorkshire and the Lion Salt Works in Cheshire.
Eight historic buildings will compete in Sunday's final for the show's prize, which is partly funded by £2.5m from the Heritage Lottery Fund.
