by Harry of Monmouth, later to become King Henry V when he was present to oversee the total destruction of the site in May 1403. Destruction Prince Henry wrote to his father King Henry IV on May 15, 1403 that "we took our people and went to a place of the said Oweyn, well built, which was his principal mansion called Saghern, where we supposed that we should have found him if he had been willing to have fought in the manner as he said, but upon our arrival we found no one; hence we caused the whole place and many of his other houses of his tenants in the neighbourhood to be burnt and then went directly to his other place of Glyndourdy (Glyndyfrdwy) to seek for him there. We caused a fine lodge in his park to be burned and all the country therabout and we lodged at rest there all that night..."
