[5] St Mary's was restored in 1867 by Henry Kennedy, the architect of the Diocese of Bangor, after the previous church was struck by lightning.

At St Mary's, the windows have geometric patterns of small panes of coloured glass as a result.

[3][5] This condition was also imposed by him for the restoration work at the nearby church of St Peirio, Rhosbeirio (now closed), where the new windows were also decorated with geometric patterns in glass.

They had an estate at Bodewryd from 1521 until 1755, when Edward Wynne (Chancellor of the Diocese of Hereford from 1707 to 1754) died without male heirs.

[6][8] The church is by the side of the road in Bodewryd, in the north of Anglesey, about 3 miles (4.8 km) from the town of Amlwch.

[3][10] It is still in use for worship, belonging to the Church in Wales, and is part of the combined parish of Llanfechell with Bodewryd with Rhosbeirio with Llanfflewin and Llanbadrig.

The window at the east end of the church, which dates from the late 16th century, is rectangular with three arched lights (vertical sections) set in a square frame.

[3] The south wall of the chancel has a brass tablet to mark money received from Queen Anne's Bounty in 1720 and Robert Wynn, rector of Llantrisant, Anglesey, in 1727.
