The Marble Church (St. Margaret’s Church), Bodelwyddan, is a prominent landmark in the lower Vale of Clwyd in Denbighshire, Wales and is visible for many miles. It lies just off the A55 trunk road.
The church was erected by Lady Willoughby de Broke in memory of her husband, Henry Peyto-Verney, 16th Baron Willoughby de Broke. She laid the foundation stone on 24 July 1856 and the new church designed by John Gibson was consecrated by the Bishop of St. Asaph on 23 August 1860 after construction at a cost of £60,000. The new parish of Bodelwyddan was created on 3 August 1860, from the communities of Bodelwyddan, Faenol and Pengwern, which until that date had been part of the parish of St. Asaph.[1]
The church contains pillars made of Belgian Red marble, and the nave entrance is made from Anglesey marble. It also contains elaborate woodwork, and in the tower can be found windows of stained glass on the north and south sides, featuring Saint Margaret and Saint Kentigern.[2] It is a popular tourist destination.
In the latter part of the 20th century the church was very distinctive because it was so white. With the passage of time, pollution has resulted in the colour becoming more grey, and therefore more like other stone buildings.
The church was in Flintshire until 1974, in Clwyd from 1974 until 1996, and since then has been in Denbighshire.
