Ruined castle near Ammanford and why Pembrokeshire is known as 'Little England Beyond Wales'

There is a lovely area of mountainside between Ammanford and Swansea which is home to a windfarm and the ruins of a Norman Castle which once guarded the violent frontier between the Normans and the Welsh.
This frontier still exists to this day in the form of the Landsker Line. It is a demarkation between areas where the concentration of spoken Welsh is higher than the area south of the line. I explain briefly why this is.

Thanks for that, I'm sure I've read in the past that Oxford returned all the remains to the then Lord Cawder who thought they should get a Christian burial, so he gave them to the vicar of Llandeilo. They interred them in the graveyard but the location has long been forgotten. Which is a shame because with todays technology, so much could be found out about them. Like the approximate age of burial , DNA , we're they related and isotope analysis to see if they were brought up and lived here or maybe travelled to the area.
