Floods and gale force winds caused devastation at pub near Truro last night.
Landlord Simon Belamy has spoken of his despair at returning from an evening out to find his pub, the Wheel Inn, Tresillian, flooded.
Mr Belamy said that the forced closure of the pub will affect his business in what is usually one of the busiest times of the year.
The fourteenth century building began to flood at 9pm yesterday evening.
Water poured in to the inn's kitchen after torrential rain and a build-up of storm debris caused one of the drains in the nearby road to overflow.
By midnight Cornwall Fire and Rescue service were called to ease the onslaught of water flooding in to the pub.
Staff worked through the night to clear the worst of the damage and the clean-up effort is continuing today.
Mr Belamy said: “The problem is there has been so much water over such a short time.
“There is still a stream of water six foot wide on the road outside this afternoon.”
The landlord hopes that the pub will be open for business this evening.
