Prehistoric caverns at Stonehouse

I recently came across a cutting from the Evening Herald from the 9th November, 1960. It carries a report about prehistoric caverns at Stonehouse and reads:

'Stonehouse's prehistoric limestone caverns, discovered in the 18th century and since lost to modern knowledge have, it is believed, been rediscovered by builders excavating foundations for a new warehouse in George Street. Directing a pneumatic drill into limestone boulders, a workman found the rock giving way to expose a 10ft shaft with two long fissures squeezing from it. Remains of prehistoric rhinoceroses, horses, oxen, deer and other animals were once found in the caverns but were destroyed when the Athenaeum was blitzed in the last war.'

I haven't been able to find any follow up to this article but isn't it amazing that this all probably exists beneath the streets of Stonehouse and it's such a shame that the remains found in the 1700s were destroyed in the war. The story of Cattedown Man is well known and his remains were discovered in limestone caves in the Cattedown area of the city in 1887. With him were the bones of 15 early humans together with the remains of woolly rhinoceros, woolly mammoth, deer and lion dating from the ice age. The remains are approximately 140,000 years old and are the oldest remains discovered in the British Isles.

Prehistoric remains have been found in Ernesettle Woods, at Mutley and Keyham as well as Stonehouse.

It's amazing what is beneath our feet but also incredible that very little of this history ever seems to be mentioned. I certainly haven't read anything at all about the Stonehouse Caverns in the last 40 years.

The location of the Cattedown caverns is meant to be a secret, for fear of fossil hunters etc, but it's well known that they are located beneath the fuel depot there. It would be incredible to be able to visit them and it seems a shame that the area is off limits to local residents.
