Holywell (/ˈhɒliwɛl/ HOLL-ee-wel; Welsh: Treffynnon) is a market town and community in Flintshire, Wales.

[1] It has been a site of Christian pilgrimage since about 660, dedicated to Saint Winefride who, according to legend, was beheaded there by Caradog who attempted to attack her.

The copper sheathing was used to cover the hulls of the wooden ships trading in the warmer Caribbean waters, giving rise to the expression 'copper bottomed investment'.

[7] The town is also served by the modern St Peter's Church on Rose Hill, consecrated in 2008.

[8][9] Holywell Junction railway station in Greenfield was a stop on the North Wales Coast Line.

[13] The community consists of four electoral wards of the Flintshire County Council local authority: Holywell is split into four distinct areas: Pen-y-Maes, the Strand, the Holway and the town centre.

The Holway, located on the west side of the town, is the largest of the residential areas of Holywell.

The nearest railway station to Holywell is now at Flint, 5 miles (8 km) away; it is a stop on the North Wales Main Line.
