It contains a 12th-century font, a 13th-century carved stone depicting the crucifixion, and a memorial to one of the officers killed when the Royal Charter sank off Anglesey in 1859.

"[3] St Eugrad's Church is in the countryside in the north-east of Anglesey, north Wales, in the community of Llaneugrad.

[3] The isolated church, set within an oval churchyard, is located at the side of a lane leading to a house and farm.

[11] The poet and historian John Williams (better known by his bardic name "Glanmor") was rector of the two churches from 1883 until his death in 1891.

[12] St Eugrad's is built in Decorated style using rubble masonry with gritstone dressings.

Alongside the doorway there is a water stoup which shows signs of weathering, and a carved stone depicting the crucifixion.

[13] The church furniture (pews, pulpit, reading desk and chancel rail) is from the 19th century; all the items are all decorated with trefoil holes.

[3] A survey of church plate within the Bangor diocese in 1906 recorded some plain silver-plated items (chalice, paten, flagon and alms dish) without inscriptions or dates.

[3] John Groome, the Fourth Officer of the Royal Charter (which sank off the east coast of Anglesey in 1859 with the loss of over 440 lives) is remembered with a stone memorial in Art Nouveau style.

[2] It was given this status on 12 May 1970, and has been listed as "a simple rural church (characteristic of the island)" which is "substantially 12th-century in character and fabric".

Cadw (the Welsh Government body responsible for the built heritage of Wales and the inclusion of Welsh buildings on the statutory lists) also notes the chancel arch, commenting that it "represents a rare survivor of an early building date for the region", the 13th-century cruxifixion stone and the 16th-century chancel roof and chapel.

[3] The 19th-century Anglesey historian Angharad Llwyd described the church in 1833 as "a small but stately edifice, of lofty proportions and venerable appearance.

"[16] The clergyman and antiquarian Harry Longueville Jones visited in 1844, and later wrote that "this little edifice is one of the simplest in the island", although he added that "the plan of the building has been rendered very anomalous" because of the erection of the chapel, "as large as the nave", on the north side of the chancel.

[17] At the time of his visit, he said that the church "was in a state of great neglect" but deserved to be "carefully preserved" because of its "architectural peculiarities".
