The abandoned school, which has been the source of many a legend and rumour in West Kingsdown, will be knocked down after closing 11 years ago – once the spooky spectres have been evicted.
It is claimed the 1940s building is haunted by priests who were sacrificed nearly 80 years ago – after the owner turned to Satanism.
Ghostech Paranormal Investigations have been appointed to find out for certain whether it is actually haunted, reported the DailyStar.
Ghostech are renowned for using a range of expensive and complex equipment, including digital recorders, electronic voice phenomena and cameras with colour spectrums.
Lead investigator and presenter Jeff Young, 52, said: “We are going to gather as much overnight evidence at Stacklands Retreat House as we can.
“We went there in the day time, and when we set up our cameras we picked up a woman’s voice saying devil worshipping had been going on – and there were orbs flying around my feet.”
The team tasked with probing supernatural powers existence at haunted places explored several places across the UK.
Jeff tracked down the death certificate of the allegedly Satanic owner and found some prayers which used to be recited at the house.
