NARROWBOATS will be unable to take a trip down the Llangollen canal until Easter due to the collase of a wall.
The canal, which shot to international prominence last summer when Hollywood couple Harrison Ford and Calista Flockhart took a cruise holiday along it, has been badly damaged by the incident and many boats have been left stranded by the resulting low water levels.
The problem was caused by a wall collapsing on the Hampton Bank stretch of the Shropshire Union Canal which feeds into the 200-year-old canal at Llangollen.
Engineers say a 130ft-long stretch of wall fell, flooding neighbouring fields.
British Waterways believe the damage will cost £500,000 to repair and could have a bad effect on tourism.
'The alarm was raised by a boater who noticed the water was running in the wrong direction,' said British Waterways spokesman David Baldiccino. 'The collapse is about the size of a house and we will erect a temporary dam to patch it up while repairs continue.'
Llangollen is one of the most popular canals in Britain. This year a £1.9m, 32-berth marina was built on it to ease congestion.
