BURSTS, boards and bats all conspired to put one of Chorley's top attractions out of action.

Astley Hall was forced to shut after what appeared to be a routine burst pipe repair turned into something more complicated.

Chorley Borough Council, which runs the historic building, discovered new lead filler pipes and filler tank for the heating system were needed.

Despite a busy period, the Grade I hall was shut on safety grounds because the work meant removing floorboards and having no heating.

Experts English Heritage were consulted. Maria Smith, hall curator, explained: "It's very important in a Grade I listed building that the rooms remain at a constant temperature to keep our local treasures in good condition. Because of that there was a need for urgency to get the work done.

"But when we looked at replacing the old tank we found it wouldn't fit through the door because a huge iron girder, which helps support the building, was put in in 1984."

The old tank had to be cut up without causing sparks or vibrations which could upset the plaster ceilings. Structural engineers were also called in as beams supporting the new tanks are 400 years old.

But then a long eared brown bat roosting just above the water tank in the attic. "This warranted a visit from English Nature to rehome the bat to another part of the attic space," added Maria.

This week councillor Mary Wilson, executive member for community services, confirmed the hall was back in business. "In the short period since the closure we've had school visits, two weddings and a Harry Potter Halloween event, plus the public coming."

Jamie Carson, the council's head of culture, sport and community development added: "We still need to replace the tank, but this will take place during normal closure times and there will be no inconvenience to the public."
