Ruined Plas Gwynfryn mansion, Gwynedd, hit by fire
Plas Gwynfryn was once the home of a Conservative politician who lost an election to David Lloyd George
The remains of 19th Century country house that was gutted by a blaze more than 30 years ago has been hit by fire again.
Plas Gwynfryn, at Llanystumdwy, near Criccieth, Gwynedd, was once the home of Conservative MP Hugh Ellis-Nanney but was destroyed by fire in 1982.
North Wales Fire and Rescue Service said the ground floor of the derelict manor house was "well-alight".
Crews from Porthmadog, Nefyn and Pwllheli were called around 16:50 BST.
In 2011, the house was one of nine historic Welsh buildings whose heritage campaign group Save Britain's Heritage said were at risk of being lost.
