Llanfihangel-y-Pennant is a hamlet and wider, very sparsely populated community (which includes Abergynolwyn and Tal-y-llyn) in the Meirionnydd area of Gwynedd in Wales. It is located in the foothills of Cadair Idris, and has a population of 402,[1] reducing to 339 at the 2011 Census.[2]
Nearby is the ruined castle of Castell y Bere, a stronghold of the Welsh princes of Gwynedd in the 13th century.
In 1800, Mary Jones walked barefoot from the village to Bala to buy a Welsh Bible.[3] This led to the formation of the British and Foreign Bible Society.[4] Mary Jones World, a heritage centre about her life is located near Bala.
