This military effigy of Meurig ab Ynyr Fychan lies within the church of St. Mary, Dolgellau. Meurig ab Ynyr Fychan was an ancestor of the Nannau and Hengwrt families. He served as 'rhaglaw' or lieutenant of the commote of Tal-y-bont, Merionethshire, from 1332-c.1339/40, following in the footsteps of his father, Ynyr Fychan, who reputedly captured Madog ap Llywelyn in 1295. The inscription around the shield reads: HIC IACET / MEVRIC FILIVS / YNYR UYCHAN ('Here lies Meurig son of Ynyr Fychan'.)

St Mary's Church is located on the edge of the old town in Dolgellau, Gwynedd, West Wales. The church is on an ancient site and there are records of it in 1254. The current church is Early Georgian and was completed by 1723. Both the style of the church and the materials used to build the church are unusual for this part of Wales. Dressed slate stones have been used to construct the nave, and a mixture of rubble stone and slate for the crenellated tower. The large arched windows have a distinctive style with the corner stones lapping each other log cabin style. The tower was probably begun in 1727, it has two stages with arched openings similar to the windows of the nave.
