Llanegryn is a village and a community in Gwynedd, north-west Wales. It was formerly part of the historic county of Merionethshire. It is located within Snowdonia National Park south of the Snowdonia (Eryri) mountain range. Travelling by road, it is around 4 miles (6 km) north-east of Tywyn and 17 miles (27 km) south-west of Dolgellau. The nearest railway stations are at Tonfanau and Llwyngwril, both less than 3 miles (5 km) away.

The rood screen is a common feature in late medieval church architecture. It is typically an ornate partition between the chancel and nave, of more or less open tracery constructed of wood, stone, or wrought iron. The rood screen was originally surmounted by a rood loft carrying the Great Rood, a sculptural representation of the Crucifixion. In English, Scottish, and Welsh cathedrals, monastic, and collegiate churches, there were commonly two transverse screens, with a rood screen or rood beam located one bay west of the pulpitum screen, but this double arrangement nowhere survives complete, and accordingly the preserved pulpitum in such churches is sometimes referred to as a rood screen. At Wells Cathedral the medieval arrangement was restored in the 20th century, with the medieval strainer arch supporting a rood, placed in front of the pulpitum and organ.
