Holton Heath Laboratories, nr Poole, Dorset

It’s not often I go exploring on a Saturday afternoon in the middle of the day. It’s usually fairly difficult to get in anywhere because of the higher volume of traffic or pedestrians and a lot of amateur explorers head out on Saturdays to the latest “tourist spot” and get caught by security!

So…with all that in mind, we went exploring on a Saturday afternoon! Our focus was in Dorset again, at the abandoned Royal Naval Cordite Factory site, the Holton Heath laboratories in particular. Used in the process of making cordite for shells during World War 1 & 2. Opened in 1916 and laid derelict since the late 1990′s.

After a stroll around the perimeter fence it was clear that there had been a recent tightening in security. New CCTV signs were up and a lot of broken fence posts had been replaced (since the last time we were here in 2009). We’d pretty much given up when we spotted our access – staring right at us! “There’s always a way in!”

The labs have been pretty much stripped of anything with any interest. Either by the decommissioning company or by thieves. There’s plenty of rooms and buildings which are still locked up – just waiting to be explored. Alas, that’ll have to wait for another day.

    FYI – drove past yesterday afternoon and there was a lot of police with dogs round the site.

    Hi Adam,

    Just visited there for the first time yesterday. Access was surprisingly easy! Sad to say that most of the newspaper clippings have stripped away, the windows have been smashed in and the weather hasn’t been kind. It’s sad to see the deterioration, this place has crumbled even since you visited.

    Another thing is that all of the buildings are now unlocked, most kicked in or the doors have literally been smashed through. Shame really.

    Good fun explore though, I want to find more local stuff like this – I found out about the Poole Power Station, it’s a shame that they demolished it a long time ago.

    Hey Adam,

    I’m heading down to the site *****, have just spent hours doing research on the place and your page has been so useful, just wanted to say thanks for sharing! Hoping tomorrow will be a good day :)

    Hi there Adam. I went up today around the industrial estate but to my utter disappointment couldn’t seem to find the way in! Went from the far end of the estate all the way to the Holton heath train station, the problem was that I didn’t really know where to start! Would really appreciate some pointers towards the correct way in. Drop me an email please,

    Hi Adam,
    I am a very keen adventurer, especially the coast and abandoned buildings…
    I do not work for anyone but myself… I have always had a passion with old buildings since i was a kid..
    Anyway, cut to the chase, i am trying to search for places and my god its hard to find anywhere on the net!
    I would really appreciate your help please :-)

    I used to manage the steam plant maintenance in there for a company called Cosens & Co, I had an office in the main boiler house. This was in the late ’80s early ’90s. We used to do loads of military site plant maintenance all over Dorset including a massive underground nuclear bunker near Sopley… this place was HUGE.

    We used to look after the Portland bunker plant too.

    I’d love to go back & see some of these sites now… a lot were only on skeleton staff at the time waiting for closure. I wonder if the Sopley place is still active… it’s huge with two levels, totally self contained with hospital, accommodation, computer rooms, plant rooms etc. the corridors where big enough to drive a car through!

    The company did work on Portland Breakwater but I was never involved with that, more the shame. West Moors is another huge site, fuel storage facility but would have thought that is still in use, that was my last posting in ’92. I left the company before it went to the wall with all the ministry cut backs around Dorset. Keep up the good work & if you need any info on places let me know & I’d be happy to help if I can.

    • Thats fascinating Mike, thank you!

      Sopley has been on many peoples radar for a long time! As far as I’m aware it’s still live and I imagine will be for a long time! It was sold and changed hands several times. It’s reported that it’s now in the hands of an American company who don’t like visitors.

      I’d be more than happy to talk to you further about these sites and possibly others? Contact me via the contact page

    Hi Adam,

    I am a photography student and really interested in exploring this location for a landscape project I am working on.
    I just wanted to know if it is difficult to enter this premises? Could you possibly reply or email me with details as to how you got in?


  8. JC Denton says:

    hey, me and some of my friends were exploring this area yesterday and the day before. we can’t seem to find the labs/bunkers and we keep on getting lost. do you happen to have any instructions on how to get the labs?


    • Hi JC,

      Your brother Paul has just spoken with me and said you’re working for UNATCO. That’s not cool man. I’m afraid I’m not going to tell you anything!

      However… if you open your eyes and look on the Western side of Station Road you’ll find the labs. They’re really not hard to find and there’s stacks of info on the net with location details!

  9. Hey,

    seems like a pretty cool location, I was wondering if you have any information on getting to the location and getting in? thanks, ersan

  10. Nicole Schmidt says:

    Hiya – where did you find the entrance? I’m familiar with the area and I’m thinking of doing a little explore shortly. Thanks for the information:-)

    • I see you work for the council Nicole?

      • Nicole Schmidt says:

        LOLOL. If I’m on an employee list or anything like that, it’s because I’m a teacher:-) Believe me, I’m a true devotee of all things derelict and I have no desire to patch up entryways into adventure and wonder. So how about it?;-)

    There are quite a few articles about this site when it was a working RN cordite factory. I can’t recall the names of any except the Royal Navy Scientific Journal which mentioned it in some issues. There are still some huge concrete tanks which were used in the production of Acetone from acorns and horse chestnuts in WW2. As a child at junior school, we collected these for the war effort but were told that they were to be used for making medicine for horses in Russia !
    If you look for a building named “The Admiralty” on the main road near Corfe Mullen, that was the pumping station for the huge quantities of water that was required in the production of acid used in the cordite process. I can remember the level crossing near there where a railway branch line delivered coal (or coke) for the steam powered pumps.
    I visited the site in the 70′s and 80′s when it was known as “Admiralty Materials Laboratory (AML) Holton Heath.
