I still cannot answer Welsh site of Richard second's betrayal
nothing I thought I know fits

From Wikipedia:

Meanwhile, Richard was delayed in his return from Ireland and did not land in Wales until 24 July.[74] He made his way to Conwy, where on 12 August he met with the Earl of Northumberland for negotiations.[75] On 19 August, Richard II surrendered to Henry at Flint Castle, promising to abdicate if his life were spared.[76] Both men then returned to London, the indignant king riding all the way behind Henry. On arrival, he was imprisoned in the Tower of on 1 September.[77]

FLINT CASTLE perhaps?

The answer is LLANDDULAS, Chris and Doglet. Mind you, that took some finding!
