Several sinkholes have opened up at a Gaelic football club in County Monaghan, severely damaging pitches and causing cracks in the clubhouse.
The sinkholes are thought to have been caused by the partial collapse of an old mine beneath Magheracloone Mitchells GAA club.
Large fissures in the pitch and cracks in the clubhouse are evident in pictures posted on social media.

The club has been closed indefinitely as a result.
"Safety is our number one priority," said club chairman Francis Jones.
"It's not great news. We're not sure what caused it, or what happens now, but we're glad no one was hurt."

An investigation is under way after part of a disused mine collapsed in Co Monaghan.
In a statement issued this afternoon, Monaghan County Council said the subsidence occurred overnight and that a section of the main Carrickmacross/Kingscourt road (R179) will remain closed over the next 48 hours with diversions in place.
A geological team is due to arrive at the site tomorrow morning to determine the scale of the subsidence and the risk of a recurring event in the area, the statement added.
Gyproc, which runs a gypsum mine in Co Monaghan, confirmed that it is investigating the case.
The company said it is still assessing the current situation with the assistance of geological teams to ascertain both the reason for, and the extent of, the subsidence.
