[2] St Dona's Church is on a steep hill near the coast on the eastern side of Anglesey, about 1 mile (1.6 km) from the village of Llanddona itself.

[3] According to the 19th-century Anglesey historian Angharad Llwyd, a church was built here in 610, dedicated to St Dona, who lived on the sea shore nearby.

The church is entered through a porch on the south side which leads to a doorway dating from the 15th century.

The rounded doorway is decorated with figures of a bird, a dog and a human face on the left, and a cherub on the right.

The window at the east end has three lights (vertical sections separated by mullions) topped with ogee curves, and is set within a pointed arch with an external hoodmould.

One is of Hugh Williams, a Royal Welsh Fusiliers soldier of World War I who died in 1918.

[11] The other is the grave of Robert W. H. Everett, a Fleet Air Arm fighter pilot killed when his aircraft crashed on a nearby beach in 1942.

[13] St Dona's has national recognition and statutory protection from alteration as it has been designated as a Grade II listed building – the lowest of the three grades of listing, designating "buildings of special interest, which warrant every effort being made to preserve them".
