An Irish naturist was ticked off after his stroll in the hills of Provence in southern France caused consternation amongst the nuns at a local priory, police said Tuesday.

"We got several calls from one of the nuns of the Congregation of St-Jean who was quite concerned to see a completely undressed man walking around close to the priory," a spokesman for the local gendarmerie said.

The embarrassed 46-year-old apologised, telling police he had not realised he was not the only person taking in the views.
