The boards are first in Welsh, then repeated in English. This is the entire history given there:
Sycharth was the home of Owain Glyndŵr. His generous treatment of poets and bards ensured the hall, moat, orchards and woodlands were immortalised in verse and song.
He shared his family home with his wife Margaret Hanmer and their eleven children. Sycharth must have seemed a haven of peace and prosperity, yet by 1405 it had become a burnt-out shell at the hands of Prince Harry (the future Henry V).
I admit that my jaw dropped. I re-read it several times, just to ensure that I wasn't missing something. It's the slimiest piece of selective insertion of propaganda that I've ever read about him!
And it's there! At Sycharth itself, in Welsh hands, owned by CADW!
I'd been warned in advance that there was scant information available on site. I hadn't been told that what was there amassed into an insult.
Nothing is false there. It's all true. This was the home of Owain Glyndŵr, and he famously was a patron of bards. We owe much of our knowledge about what Sycharth looked like in its heyday, because Iolo Goch regularly stayed there and wrote verses about what he could see.
But was that all that Owain did? Is that why he became legendary? Because he enjoyed listening to a good harp-strung epic after a hard day's being peaceful and prosperous?
Yes, he did marry Margaret Hanmer. Though her name has been rendered here in English. In Welsh she was Marred ferch Dafydd, yet not even the Welsh language version says that.
Sycharth was a haven of peace and prosperity up to a point. The family were surrounded by English nobility, which meant a degree of diplomacy. Their house was built out of wood, while the English ones were stone. That wasn't for want of cash. The Welsh were supposed to be subordinate, so the wooden structures didn't provoke the English lords.
Owain Glyndŵr would have lived with that rankling on a daily basis.
Then the final part just left me breathless. An English prince destroyed Sycharth. It's written in the most friendly of terms. We're given Henry's pet name of Harry. We're reminded that he was Henry V of Shakespearian play fame. We are not given the reason.
You have to know why you're at Sycharth, because nothing there will leave you any the wiser.
