I posted this without seeing Jack's posting as it takes me so long to type!!
Dyserth it is. Well done Jack as this was quite hard.

Dyserth Castle was built by Henry III ( Edward I 's father) it didn't last long and was destroyed by Llywelyn ap Gruffydd in 1263 and there is little left of it as it has been destroyed by the quarry.
There's a nice walk Jack from Meliden to Gwaenysgor and returning down along the Afon Ffyddion ( Ffydd = faithful

)
to come out by Dyserth Waterfall.
If it's any consolation to anyone, I lived in Dyserth for about 7 years and didn't know that there was a Norman Castle there.
