Efforts are underway to re-open the walking trails at Rindoon in south county Roscommon.
The abandoned town is one of Ireland's most important medieval heritage sites, with access via a loop-walk.
Rindoon is built on a fortified peninsula, St John's Point, near the village of Lecarrow, on the western shore of Lough Ree.
The castle was built in the 13th century to protect an Anglo-Norman town that once had a population of c.1000 inhabitants.
The walks which stretch through the town and along Warren Point, are hugely popular with local people and also with thousands of tourists who seek out one of the most important medieval heritage sites in the country.
They have now been closed and it's understood it's related to an issue to do with insurance and liability.
Local Councillor Donal Kilduff says efforts are being made to resolve the issue as soon as possible.
A number of organisations including the National Trails office and the local authority are involved in the management of the walkways which are accessed through privately owned lands.
Shannonside news understands that all parties are working to resolve the matter.
