Sin: යකල්ල yakalla Tam: யகல்ல yakalla

‘Devil’s Rock’   NCP,  Sri Lanka.

From Sin: yak/yaka, ‘demigod, demon, devil’; and  gala, ‘stone, rock, rocky place’.

Any grotesque-looking rock merits this name-calling.

There are plenty of those here as well as Buddhist cave temples at Warana, Pilikuththuwa, Uruwala and Maligathenna. 

Yakalla sits on the edge of the Hurulu Wewa tank or reservoir.
