The Yeats Society Sligo has launched a crowdfunding campaign, saying that without increased funding its future is in doubt.
In a statement, the society said that before the pandemic, the Yeats International Summer School brought people from across the world to Sligo, and the Yeats Building offered visitors and locals alike information on the poet's inspiration.
However, the building closed to visitors and tours in March 2020 and that year's summer school was cancelled.
The summer school is online this year and the society has said its source of revenue has dried up. As an organisation without core funding, it says its future is now in peril and it is looking to raise €100,000 by September to guarantee its survival.
The society was founded by contemporaries of Yeats in 1960, and its building houses a large collection of books and other archive material which is made available for scholarly research.
It runs the Hyde Bridge contemporary art gallery, which hosts 11 exhibitions a year.
Director of Yeats Society Sligo Susan O'Keeffe said that the society had helped to bring "our poet to the people, especially for the people of Sligo".
"We've opened our doors to aspiring writers and poets discovering that first spark of literary inspiration," she said. "Our building is a place for all of us to explore Yeats' work and find our connection with Sligo’s greatest poet and to enjoy and appreciate contemporary writers, poets and visual artists."
