Built on the 7th century site of St. Marcella Church, the church is classic Vale of Clwyd twin-nave style and is largely the result of remodelling about 1500. St Marcella’s was the parish church for Denbigh throughout the medieval period. 

Exceptionally fine and well preserved, it is one of the most important churches in North Wales and contains some notable monuments. Buried inside are the map-maker Humphrey Llwyd, members of the powerful Salusbury family and the heart of Richard Clough, the Denbigh-born merchant. Outside is the grave of Twm o'r Nant, a dramatist and poet of Denbigh.

The 2026 Denbigh Open Doors Weekend launches on Friday 18 September with a self-drive Tour
of the Vale, followed by an evening lecture at Theatr Twm o'r Nant, “Restoring and repositioning Brookhouse Mill for the future”. Over the following two days, Saturday 19 and Sunday 20 September, thirty historically important sites in the locale will be open to the public. This will be supplemented by children’s workshops, guided tours and an interactive show. A booking service for events with limited places will be available through Denbigh Library, closer to the weekend. Further information will be available at -
