Wern Mynach woodland is located in Barmouth town centre, not far from the football field.
The Cistercian monks monks from the Cymer Abbey, Llanelltyd would bring their animals to Barmouth over winter to graze on the Wern's salty marshes. There are number of places in Barmouth which have been named after the monks. After the construction of the railway back in 1886, small lakes were formed at the site. A monk gave the land to the residents of Barmouth for their recreation. A football pitch was built on the site, and the rest of the land was made a landfill site. In 2005 this urban green site was created, hundreds of trees were planted, including oak, apple trees, mountain ash, broom willow, wild flowers which attract insects, birds and animals.
