Guess the Place

[MartinR]

The settlement is about 1/2 mile S of the M25, and the actual location of the quarry about a mile S of that.

[KeithG]

I think things are getting mixed up here?


What you're after is it North or South of the M25?

[MartinR]

No, the stone is called "Kentish ...stone".  Further hint: If I started at Sevenoaks and headed west to an ancient settlement with a Saxon name, where would I be?

[KeithG]

Don't know type of answer you are looking for but Bargate Stone / Kentish Ragstone was mined on Surrey and Kent border ?

[MartinR]

No, try Kentish .....
Recap:South of Chislehurst.  In the area of Fort Halstead.  Clearly an abandoned operation, dug in the mid 19thC.

hearthstone?

[MartinR]

No, you were right previously, it was a tunnel to mine a form of limestone.  Hint: the type of limestone is peculiar to this county.

Bomb Testing ?

[MartinR]

Now you're getting warmer.  Not quite chalk, but a form of limestone.

[John Walker]

Was it a tunnel to mine chalk or a tunnel for access?

[MartinR]

Not Pollhill tunnel.  The sides of the tunnel have waste from subsequent tunneling deposited in them, you can see it on either side.  The tunnel was never higher than this.  Hint: the tunnels were not used for transport or mineral extraction.  The tunnel shown is early-mid 19thC.

[John Walker]

Polhill Tunnel
Badger's Mount, Kent, UK ?

[MartinR]

FHD area, but not the Fort itself.

[John Walker]

Anything to do with Fort Halstead area?

[MartinR]

Stuart: man-made
John: you're moving away from it.  Go south from Chislehurst.
