About Holywell & Greenfield
Holywell (Welsh: Treffynnon) and Greenfield (Welsh: Maes-glas) are neighbouring settlements in the county of Flintshire, north-east Wales, forming part of the same community administrative area. Holywell serves as the principal market town, while Greenfield functions as an adjacent village. Both lie to the west of the River Dee estuary, set within rolling countryside that offers stunning views across the estuary toward the Wirral Peninsula and out to the Irish sea. The area is accessible via the A55 expressway and A548 coastal route, with bus services connecting to nearby towns such as Flint, Rhyl, and Chester.
Holywell
Holywell is a traditional Welsh market town whose name derives directly from St Winefride’s Well, a natural spring that has been the only site of continuous Christian pilgrimage since the 7th century. According to legend, the well sprang forth where the head of Saint Winefride (Gwenffrewi) fell after she was beheaded by a local prince; Caradoc of Hawarden, after she refused his marriage proposal. She was restored to life after her uncle; Saint Beuno prayed for her. These waters are reputed to possess healing properties and have been documented over many years, until the advent of modern medicine. However there are still many stories of people being cured by bathing in or drinking the well water, to this day. The town is widely known as “the Lourdes of Wales” and the well is recognised as one of the Seven Wonders of Wales. The associated 16th-century chapel complex, a Grade I listed building, remains an active pilgrimage destination and includes bathing facilities at set times.
The community of Holywell, which encompasses Greenfield, recorded a population of 8,886 at the 2011 census (with the larger built-up area at 9,808). Recent estimates place the community population at approximately 9,200–9,270. The settlement comprises distinct areas including the town centre (with late Georgian and Victorian architecture, shops, cafés, and public houses), Pen-y-Maes, the Strand, and Holway. Historically, the town expanded significantly from the 18th century onward through lead mining and associated industries. It features a conservation area in its historic core, a Grade II* listed parish church (St James’), and modern amenities including a community hospital (opened 2008), leisure centre, secondary school, and four primary schools. Holywell Town Football Club competes in the Cymru North league.
Greenfield
Greenfield is a semi-urban village located on the edge of the Dee estuary, approximately one mile north-east of Holywell town centre along the B5121. Its 2011 census population was 2,741 (rising modestly to 2,778 by 2021). The Welsh name Maes-glas translates equivalently to “Greenfield.” The village developed as an industrial hub, capitalising on the constant water flow from the stream originating at St Winefride’s Well. A paper mill has operated on the site since 1770, and the area hosted up to 80 businesses in the mid-19th century, including cotton mills, copper works, flannel production, flour milling, and later rayon factories and a sulphuric acid plant.
Today, the local economy combines tourism (centred on pilgrimage, heritage, and the natural landscape), small businesses, retail in Holywell town centre, and light industry at Greenfield Business Park and Business Centre. The area retains strong transport links, although the former Holywell Junction railway station (Grade II* listed) closed to passengers in 1966; campaigns for reopening have been noted in recent years. The surrounding countryside, including Halkyn Mountain and coastal paths, supports outdoor activities such as walking, cycling, and golf.
Shared Industrial and Heritage Significance
The Greenfield Valley, which links the two settlements, played a pivotal role in the early Industrial Revolution in north Wales. Water power from the Holywell stream drove numerous mills and factories, notably copper smelting operations established by Thomas Williams that supplied sheathing for Royal Navy vessels, including HMS Victory. Remnants of this industrial past are preserved within the award-winning Greenfield Valley Heritage Park, a 70-acre woodland site featuring lakes, streams, ancient monuments, ruined mills and factories, and an agricultural museum with relocated historic buildings. The park also incorporates the ruins of Basingwerk Abbey, a Cistercian foundation established circa 1132 and dissolved in 1536, now managed by Cadw. Visitor facilities include woodland walks, a giant adventure playground, a mystery maze, resident animals, and a tea room. The park is open daily from March to November and interprets 2,000 years of local history, from prehistoric and Roman periods through medieval monastic life to 19th-century industry.
Contemporary Context
Today, the local economy combines tourism (centred on pilgrimage, heritage, and the natural landscape), small businesses, retail in Holywell town centre, and light industry at Greenfield Business Park and Business Centre. The area retains adequate transport links, although the former Holywell Junction railway station (Grade II* listed) closed to passengers in 1966; campaigns for reopening have continued since 1971. Picturesque walks between Holywell town centre and the Greenfield valley heritage centre have been established since 2014, the route incorporates the historic remains of the mills along the valley. The surrounding countryside, including Halkyn Mountain and coastal paths, supports outdoor activities such as walking, cycling, and golf.
