Castle Hill

Castle Hill first came to our attention in early 1995. Information came from a former Allied Intelligence Officer during WW2. He said there were a number of entries on Castle Hill. An ex-serving member from 11 Stores Group mentioned he used to pick up type writers from this location to be repaired.

Recently we visited the West End quarry and  Green Street sites.   The Green Street site and SES complex are Ezekiel Elliott Authentic Jersey now void of any visible signs of the existence of Ezekiel Elliott Womens Jersey underground structures.   But the quarry area still has the foundations of the old crushing and processing plants.  We were told by a local that there was a tunnel door there, that could be seen to this day. He called it the “Blue Doors”.

At the top quarry sits the foundation to what looks like the old crusher plant. On this foundation is blue graffiti. According to our source, this was the doors. But an inspection of it revealed nothing to indicate there were any doors there, or that it’s location could have been used as an entrance.

Our investigation went cold until recently, when we were contacted by a man who said he and his brother used to play around the quarry area when they were kids.    His brother knew of doors at the top quarry that he had seen when playing around there.   They had both been up there recently, but were unable to find the place they had seen the doors.

A Google photo of the quarry was sent to us, with areas we had been investigating.   What was the arch structure was between the top and bottom quarries next to the so called “Blue Doors”.

To date, we had not been able to find anyone who could explain what that arch was used for. So we set out to find any photos that would shed light on what the arch was used for.

After scouring all the old aerial photos we had access to, we finally found what we were looking for.

The two photos below are taken from Google maps. The circled area is the arch structure.

The first image is a bit hard to make out, but shows where it is in the quarry. The second Ezekiel Elliott Youth Jersey photo is a closer view, where you can see the structure and the shadow on the ground clearly shows the arch.

Below are a run of aerial photos

Image 61 (above) shows clearest, the arch and crushing plant at the top quarry. But all three photos show the quarry while it was operational and all show the arch & crusher plant.

Below is a blow up of image 61 which clearly shows a pipe or tunnel running back into the hill, with a conveyor coming out which leads to the bottom quarry. Is this the exit point of the all rock cut out of the hill as the tunnels were constructed?


We are looking for anyone who worked in the Quarry or anyone who can remember where any tunnels or entrances are. If this you, please contact

  1. Hi my name is Ian I recently found your video of Bankstown fighter Squadron HeadQuarters on YouTube it seems like nobody realises that on the corner of Marion Street and Edgar Street on the foot path there’s always been an entrance which was the emergency exit to The Bunker with a green steel door, it has covered up with a dirt mound and trees put on top you will notice there is a mound on the corner and there must be another entrance as well as friends of told me many years ago they went through an air vent which went at a 45 degree angle for a long way then it drop down about 10 feet into the bunker, the same one that Burke’s Backyard went through back in the 80s or 90s and there is a video somewhere of that which shows a lot of the inside and also on six Maps 1943 Matt’s you can actually see the bunker before it was covered up with dirt when it’s completely on show you can see they haven’t even finished it completely yet and there looks like another emergency exit going towards south of Marion Street so they must have had to emergency exits by the look of it unless that is the vehicle Entrance.
    And by the way did you ever go back to Bankstown bunker after that video and excavate anything and take any other photos or videos as I’m very interested in it because you said you will have to come back and investigate more.
    I am very interested in all the history as I lived not far from there you can also see up on the hill remnants of indentations in the ground where the anti aircraft guns where .

    Also have you guys been out to investigate the Gestapo headquarters at Narrabeen a very interesting site with a lot of History they’re still remaining I know a lot about this as I have been researching it for a while as I am very interested in all the military history in Australia especially in New South Wales as my father and his three brothers all served in World War 2.
    We also have wooden tank traps and one tetragon concrete pyramid still on the north shore in plain view.
    Also I’m very interested in now inland last line of defence systems as last year visited the only remaining one intact near Ebor Falls very amazing that it’s still all there and even the people that lived not far from there don’t even know about it it’s existence, and there is no graffiti at all on the site also Dorrigo Mountain has a lot of history from World War 2 as well as was another part of our last line of defence it has tunnels all the way through it which had explosives in it to blow the mountains up not sure if you know about all this but this is first hand off residence that they grandfather’s help build the defence systems.
    One more thing that I have not visited yet is the fuel dumps down at Goulburn which will be on my list when the weather cools down a bit and the World War 1 trenches near Goulburn as well which was the training ground for all the officers in World War 1 for trench warfare.

    Would love to hear from you,
