The Westport Hotel Group - which operates the Castlecourt Hotel, Westport Plaza and Westport Coast hotels - is to close for three weeks.
The hotels, which are run by the Corcoran family, will close until 28th October.
The owners say it's with great disappointment that, due to the introduction of level 3 restrictions, they have announced the temporary closure of the hotel group.
Anne, Joe and Anna Marie Corcoran say that, in these challenging times, they have a duty of care to their team, customers and wider community, and they believe closing their doors temporarily is the right thing to do, while they look forward to welcoming new and returning guests in happier and healthier times.
Anyone with queries can contact the hotel group by phone or email.
The Westport Hotel Group is a major employer in the area.
