The Killybegs Maritime and Carpet Making Heritage Centre is to close.
The committee which runs the centre revealed the building which houses the centre has been sold with vacant possession.
The committee said they are not in a position to legally challenge this.
More than 75,000 people are estimated to have visited the centre over the past 15 years.
A spokesperson said “The building has been sold with vacant possession and it was unfortunate that we were not in a position to legally challenge this.
“The past 15 months has not helped our cause as we had to close because of the Covid19 pandemic and have had to remain closed.
We have been merely the custodians of this unique history of our town. A place of employment since the 1800s for the women and some men of the area. We are so grateful for the support we have received since we opened in June 2006.”
The committee thanked everyone who has been supportive of the centre.
“We would like to thank the business community who were so supportive. Thanks to the hotels and guest houses for financial support when asked and for sending their guests. The Tourist Office, Cruise Committee, shops, coffee shops and restaurants who promoted us with all their customers.
“To the general public for sending relatives and friends to visit and leave with great memories. Many excellent reviews were recorded in our visitor books. We have been open almost 15 years to the day and have had in excess of 75,000 visitors.”
“A special thanks to Colin Mabon and Ann Marie Bourke at the Killybegs Community Employment Scheme for the excellent staff we have had over the years. They all developed such passion and love for the project. Many coming in on a voluntary basis. Some of whom are no longer with us. Remembering Freda Gillespie and Maeve Shovlin RIP.
“To the fishermen who offered their expertise to guests on the maritime side, particular thanks to Conal Breslin. The Killybegs Fishermans Organisation that came on board were invaluable. Remembering Martin Howley RIP.
“To Donegal County Council from whom we received grants at various stages. The Leader programme which was the start-up funding.
“Donegal Carpets have graced the floors of Aras an Uachataran, Parliaments worldwide, The White House etc.
“We will find a home for the fishing exhibition, memorabilia and the simulator in one of the new developments in the town under the Regeneration Programme.
“The Carpet Factory is a protected structure as are the looms so therefore this building should stay intact and preserved until such times as the new owners decide upon a positive outcome for our much-valued heritage.
“We are so sad that it has come to this. We did all in our power to “stay the course” but that was not possible. We look forward now to the next phase in this historic building.”
Reacting to the news local county councillor Niamh Kennedy described the closure as “very sad.”
