Demolition works are underway at a disused former mental health hospital weeks after a suspected arson attack.
Ribbleton Hospital has been plagued by anti-social behaviour since its closure in 2015.
Workers have started the process of stripping asbestos from the former mental health facility before bulldozers move in over the coming weeks.
The Miller Road location is up for sale, Lancashire Care Trust has said, although its future remains uncertain.
Barry Cleminson, project manager, said: “The site will be levelled by mid-December, once the asbestos stripping has taken place, we will move in with the heavy machinery.
“Bradley Demolitions has been on site for two weeks with the stripping process expected to take a further fortnight.”
Earlier this year, when permission to level the site was granted, Lancashire Care NHS Trust said the building had attracted a “large amount” of vandalism.
And last month fire crews were called to the Miller Road site to douse a blaze started in a stair well. Police were been notified of the suspected arson attack, the Lancashire Fire and Rescue Service said.
Patients at the 28-bed unit were moved to The Harbour - a 154-bed purpose built facility on Preston New Road - in March 2015, bringing to an end more than two decades of mental health care at the site.
Speaking earlier this year, an NHS spokesperson said: “The future use of the site will be determined by a new owner, at this stage we are too early in the proceedings to know.”
