Officers were called to the address in Cleveland Road after workmen made the eerie discovery in a cellar on Friday (August 15).
Renovation work on the home was suspended while Crime Scene Investigators (CSI) carried out a forensic examination of the property.
Work is ongoing to identify the remains, which Lancashire Police have confirmed as human. However, the force believes the bones belong to a historical burial site on the grounds of the terraced home in Cleveland Road.
“Whilst we are keeping an open mind, there are not thought to be any suspicious circumstances,” a police spokesperson told the Blackpool Gazette today.
