Hendregadredd Manuscript

The manuscript was long part of the library at Hengwrt, assembled by the antiquary Robert Vaughan (d.1667).

It was unexpectedly rediscovered in 1910 in a cupboard in a disused bedroom of the mansion of Hendregadredd near Porthmadog: a note found inside, written by the Archdeacon of Merioneth, Richard Newcombe (1779-1857), stated "I have long been in possession of this Welsh MS. but forget where or how I obtained it".

[2] It is now part of the collection of the National Library of Wales with catalogue number NLW MS 6680B.

The Hendregadredd Manuscript was probably written at the Cistercian abbey of Strata Florida in Ceredigion.

These include a poem possibly in the hand of Dafydd ap Gwilym himself, the best-known poet of his time, who was closely associated with Strata Florida.
