Joan Bakewell presents a new series of poetry programmes, in which she seeks out the most treasured poetry in some of the UK's great libraries.
The National Library of Wales, Aberystwyth
The Welsh poetic tradition is extremely rich and fiercely nationalistic.
Joan looks at some of the oldest Welsh poetry in existence, as well as coming across some interesting Bardic chairs, poetry written on prison toilet paper.
Poetry is read in both Welsh and English by poet Gwyneth Lewis.
