St Hilary's Church in Llandudno opens its doors free of charge on September 14 from 10am to 1pm.

The church, originally built in the 6th century by Prince Maelgwn Gwynedd of Deganwy Castle, showcases the history of local families - the Wynnes, Mostyns, Prendergasts, and Pughs.

Offering more than 60 war memorials and burials, historians and visitors can trace family trees with accessible registers.

The prince is reported to be buried under the south door, adding to the rich historical tapestry of the venue.

The churchyard boasts a wide range of wildlife habitats as well.
