Cave boasts UK's biggest chamber

A cave believed to have the biggest chamber in Britain has been unearthed in the Peak District in Derbyshire.



Titan's main shaft is 460ft (140m) deep, as high as the London Eye, sculpted out of limestone by rain water over millions of years.

Local potholer and underground explorer Dave Nixon led the team that discovered it, near Castleton.

He began searching for it after reading an account by an obscure 18th Century academic in a university library.

Titan is nearly 197ft (60m) higher than the previous record holder, Gaping Ghyll in the Yorkshire Dales.
