[July, 2011] To be honest, in this bus tour in Ireland I could not understand the guide very well.
His Irish English was far beyond my listening comprehension ability.
So I am not 100% sure but I think this ruin of fortress was situated around Cahersiveen in Ring of Kerry.
It is more than 1000 years old, but thinking about it, the Nara era in Japan started in 794, and Roman Empire was flourished before Christ.
This part of the world developed very slowly indeed.
