Work to renovate the thatched roof of a "rare and ancient" Grade II-listed tithe barn has been completed.
The building in Landbeach, Cambridgeshire has been dated to the 16th Century, but it is believed its origins could be medieval.
The Tithe Barn Trust raised more than £200,000 for the work after starting an appeal five years ago when they took over the building.
Gemma O'Shea from the Trust said it was "a time for celebration".
"I can't wait for everyone to see the barn once it's completed," she said.
Tithe barns were used to store a tenth of a farmer's produce, such as wheat or barley, which had to be paid to the Church as a form of taxation.
The Trust said the one at Landbeach was the only one in Cambridgeshire with an elm frame, thatched roof, timber granary and brick threshing floor.
Carpenters also carried out repairs on the timber frame, but the barn doors still need repairing and re-hanging.
Ms O'Shea said it had been given "generous donations from the public" and grants from organisations including almost £100,000 from the National Lottery Heritage Fund.
Phase Two of the project will involve fundraising for electricity, running water and toilets on the site.
It is hoped the barn will eventually be used for weddings, dances, community events and school visits.
Ms O'Shea said the aim was to "ensure the long-term survival of the rare and ancient tithe barn, by breathing new life into the site, for everyone to enjoy".
An event celebrating the completion of Phase One will be held at the barn on Saturday, 28 March.
