Armed with an underwater camera, I had hoped to find an arched-roof tunnel going as far as the eye can see and descending at an angle of about thirty degrees in the direction of Quarter Colliery.
A similar arrangement can be seen in a photo of an Airshaft at Muiravonside Pit:
From Falkirk Museum & Archives
View of a shaft sloping at a shallow angle into the ground. It is lined with bricks with an outer cement coating, and terminates in a brick arch.
Text on original print – “Air pumping station. 26/958 760. Showing brick lined air shaft.”
The Torwood Blue Water Pool’s Brick Arch was heavily choked with weed but I managed to get an interesting detail.
The Arch is just an opening in the circular wall containing the pool. Behind the arch on the left hand side can be seen a plain brick vertical wall that appears to be higher than the arch. My Airshaft Theory may be looking a bit shaky.
As time permits, my next task will be to clear the weed inside the arch, with special attention to the vertical space just behind and above the arch. When the water clears (probably a week) I will try for some more informative photos.
Weed re-growth on the inner wall of the Pool has now obscured the three 5 inch pipes — I will uncover those.
During my sub aqua exploits, John Gillespie from Denny appeared on the scene. John, a very fit 70 year old, remembers visiting the pool when he was about 14 years of age.
John recalls with absolute certainty that around 1954 there was a continuous wall about 5 feet high going all the way round the pool. There were no breaks and the only way he could see the water was to pull himself up to look over the wall.
My own memories of around 1962 were of a ragged broken wall with bits about 3 feet and bits at ground level but I was not sure if I was inventing the memory. I certainly remember kneeling at the side of the pool and watching beetles swimming all the way to the bottom.
In light of the above, I must discount a previous account in this investigation that says the pool looked the same in the 1930’s as it does now.
Another important bit of information that John came up with is that there were no planks lying around the pool in 1954 — the planks seem to have been a modern addition.
