A reconstructed Viking longhouse used by schoolchildren in Lancashire has been destroyed by vandals.
The longhouse was built using recycled timber
The structure at Penwortham, built from recycled timber and shingles, is part of Lancashire Wildlife Trust's (LWT) education programme.
It was torn down and then burnt, after burglars cut through the locked gates.
The LWT said it had "worked hard on a shoestring budget" to create the longhouse and appealed for donations and volunteers to help rebuild it.
School parties travel from across Lancashire to experience a day in life of a Viking community at the house.
Ric Campbell, the Trust's head of education, said: "If anyone out there can spare a little money or materials, or if you have skills that would help us, please get in touch."
