Looking into Blackheath's mysterious cavern (Huge Cave system under London)

Land around a mysterious cavern underneath Blackheath could soon be under investigation.

Parkman's, the surveyors who investigated a six-foot-wide crater that appeared in the A2 at Blackheath Hill last April has said further checks on land stability in the area are needed.

Decisions on their report were to be made by Greenwich council last night.

But the council, which would apply for a grant from English Partnerships to cover the costs of the investigation, is not yet sure how much it will cost.

The collapse of the A2 into chalk pits after subsoil washed away triggered traffic chaos, hundreds of people were evacuated from their homes, and repair work spanning nine months cost £2.25million.

Honeycombs of chalk workings are known to exist under Blackheath, and rumours and stories about one of the largest, known as the Blackheath Cavern, located below The Point, have circulated for centuries.

The ancient chalk workings are said to have been shelters for the Saxons and later for 15th century rebels. Rediscovered in 1780, the cavern became a tourist attraction and a venue for wild parties but were closed down hurriedly in 1854 after a "disorderly masked ball".

Its existence slipped into legend until 1939 when, after attempts in 1906 and 1916, Greenwich council located an entrance using "electrical resistivity" and sank a shaft down 40 feet.

At that time a Kentish Mercury reporter entered the cavern from the back garden of a house in Maidenstone Hill, along with council representatives considering its use as air raid shelters.

He reported there were in fact three linked caverns a total of 59ft long and the floors were littered with broken bottles.

But concern about the stability of the area has resurfaced following last year's collapse.

Greenwich council undertook remedial ground works to stabilise council-owned Cade Tyler House after the road collapse and carried out investigation work around Undercliffe House and A2 where it meets Maidenstone Hill.

In a recent letter to residents, David Jessop, the council's assistant director of transport and highways, said: "Bearing in mind the recent subsidence and some of the recent investigations, I think it is prudent that the condition of the Blackheath Cavern and the extent of any workings in the immediate vicinity are thoroughly investigated."

A council spokesman said: "There is no suggestion of any immediate risk to properties as far as the council is aware.

"It should be stressed that responsibility for the land and buildings upon them is with the relevant property owners. But the council considers it has a wider public responsibility to take a lead in bringing about these investigations."

I found this to be a cool and interesting article.

Don't you guys watch Buffy? This is clearly a Hellmouth waiting to happen!

The illuminati headquarters obviously. Seriously though, it would be a great place to do a dig. There are probably old coins, bottles, "trash" that would be very valuable there for historical artifacts.

A2 Brute? Interesting article. A couple of days late to commemorate the Ides, but still a timely lesson for all. Chalk, I can dig it. LOL

Above ground the fog and cobblestones. Underground the mysterious rooms, scurrying rats and strange broken bottles.

Where's Vincent Price when you need him?

That is inexcusable! LOL!

Good place to detonate a terrorist bomb if there's anything of importance above.

Thanks for the ping. I wonder how old the caverns are and what interesting things will be found?

It's Quatermass' pit (there were two versions, one for TV, one a Hammer Films production, along with the Penguin edition).

Heh. Just put it in my Netflix queue.

Saw this on Chiller Theater or Zacherly probably 40 years ago. Love those World in Panic! Cities in Flames! films.

Great movie...it really gave me the creeps. So this cave system could be the hive?
