Llanrhaeadr-yng-Nghinmeirch is a small village in the Vale of Clwyd, on the A525 between Denbigh and Ruthin, known for one exceptional survival: the Tree of Jesse window in its parish church of St Dyfnog, dating from 1533. The window depicts the family tree of Christ in glowing medieval glass, and is widely regarded as the finest stained-glass window in Wales, and among the best in Britain — a near-complete work whose sophisticated facial detail is often judged more accomplished than the slightly earlier glass at Gresford and Llandyrnog.
The church itself dates from the 13th century, though much of what survives was rebuilt in the 15th and 16th centuries. It's dedicated to St Dyfnog, a 6th-century Welsh saint associated with a holy well beside the church that became an important pilgrimage site in the 17th century, its waters once believed to have healing properties.
Denbigh's own visitor trail includes an entry for 'St Dyfnog's Church' among its historic attractions — this is that same church at Llanrhaeadr, just a short drive from the town, and well worth combining with a visit to the village itself.
Llanrhaeadr-yng-Nghinmeirch's parish church of St Dyfnog is celebrated for its magnificent Jesse Window, a stained glass masterpiece installed in 1533 depicting the genealogy of Christ, and considered one of the finest surviving examples of pre-Reformation stained glass in Wales. The church also retains its 15th-century roof and other features that survived the Reformation and Civil War largely intact.
Beside the church, St Dyfnog's Well sits in a wooded grove and was for centuries a site of pilgrimage, believed to have healing properties and associated with the 6th-century Welsh saint Dyfnog. The combination of church, well and woodland setting makes Llanrhaeadr a rewarding short detour from Denbigh for anyone interested in Wales's medieval religious heritage.
