Found a great website for those interested in abandoned places. I've even found some from London
These are the reminants of the Parkwood Pavillion in the woods behind the hospital. I believe it was used as a recreational facility for patients. Up untill recently there was even a radar museum there.
And then there's the old London Asylum for the Insane, behind the current mental health centre on Highbury
This is the Marlboro Apartments , at 414 King St.
The recently abandoned McCormick Factory
Anyways, there's lots more on the website, hope you enjoyed my selections!
