Harperbury Hospital was a former mental health and learning disailbities hospital built on the remains of world war 1 hangers.  A large part of the hospital was closed in 2001 and those bulidings have rapidly deteriated over the years. I visited most recently in 2013 but since then a new purpose built building has been established in the middle of the original site – leaving all the old buildings now closed and derelict.

The new building retains the newer name of ‘Kingsley Green’ and continues to offer a variety of services.

    Hi so I live in shenley and a few years ago I went on a bike ride and stumbled upon this place, it was very scary and ghost like. It has now been demolished and a new hospital built next to it called kingfisher court, with a. New housing development in front. The road is called lime way if your wondering.

    I was one of the nurses, who worked there from 1981 till 1996, and all of us have had been offered early retirement, or reapply for our jobs. It was about to be closed, and I have not been back since I left Borehamwood since 1998. Anyone know what has become of the old hospital, and I will be most appreciated, if someone will filled me in.

    Hi we want to go there please follow and dm my Instagram @pyschoo.bitch_ if anyone’s interested

    Sorry everyone, due to multiple arson attempts, all the buildings there have been boarded up, on site security and alarms have been beefed up massively. The only way in, is through the service tunnels. The hospital buildings are placed in a big ‘D’ Shape. – Follow the path round to the middle of the curve and you will find an open man hatch – Thats your way into all the buildings. The tunnels are long, dark and very asbestos-y. I dont know how you’d get out of the buildings you climb into though.

  • Spoilers Pond, June 2, 2017 @ 19:56

  • Holly, April 14, 2017 @ 19:14

    I tried to go here today, I needed some photos for a project. Wish I could of gone with someone who knows what they’re doing, we got caught by security! I think we went in the wrong way entirely, but I really want to go back and try again. Does anyone know the best way to get into the premises?

  • tumbles, April 2, 2017 @ 20:28

    I know people who went at weekend with no issues. Maybe its being overplayed..

  • Kitz, March 25, 2017 @ 21:20

    Luke, any updates on the situation? We went there last month (Still a newbie to the tunnels – would love to go back to explore them!) and could see visable signs of squatters in one of the buildings that “closed” in 2011 (if I’ve got my dates right)

  • Luke, March 13, 2017 @ 00:27

    Don’t go there’s a dangerous man living there this youtuber been attacked 3 times a police investigation is currently underway

  • Lukas, December 24, 2016 @ 10:01

    If you don’t mind a bit of asbestos and aren’t claustrophobic, there’s some service tunnels running under the complex that nicely link up several of the buildings. We traveled from the first building with the car park out front all the way to the empty hall, bypassing security entirely.

  • tumbles, October 2, 2016 @ 18:56

    There is more than one way in

  • Kane G, September 30, 2016 @ 12:09

    hey people! this place looks cool and i know where it is but theres only one way in and one way out? how did you get in without being caught! id loveto know
