Milverton Quarries

Overview

Milverton Quarries sit just a stone’s throw from the seaside town of Skerries, on the north‑shore of County Dublin. The quarry is a dramatic landscape of sheer limestone faces that tumble into a striking turquoise pool, a colour that has drawn photographers and nature lovers for decades. Although the site is still an active extraction area, the historic lime‑kilns and the surrounding wildlife make it a compelling stop for anyone exploring the Irish coast.

History

The quarry’s industrial story began in the early 19th century when lime‑burning was the dominant activity. Two massive masonry lime‑kilns once dominated the site; each measured roughly twenty‑five feet square and thirty feet high, with ramps on two sides that allowed horse‑drawn carts to deliver broken limestone to the top. Inside, a cylindrical chamber about twelve feet in diameter was lined with fire‑brick and fed alternately with layers of culm (a special type of coal) and broken limestone. The fire would travel upward, calcining the stone into quicklime, which was then raked out through a square opening at the base.

The quicklime produced here was used locally for agriculture, construction and even as a disinfectant. Over time, the lime‑burning operation ceased, but Milverton Quarry remains in operation under modern ownership, while its historic kilns stand as silent witnesses to a bygone era.

Operator & Products

Milverton Quarries Ltd, founded in 1938, is the current operator of the site. According to the Geological Survey of Ireland’s Quarry Directory, the company supplies a range of limestone products, including dimension stone, aggregate and agricultural lime. The quarry is listed under the “Limestone” rock type and produces material for both construction and landscaping purposes. The operator also runs an inert‑waste recovery facility on‑site, managed by Roadstone Dublin Ltd, which back‑fills the worked‑out void with clean construction soil and stone.

Building material legacy

Limestone from Milverton Quarries has been used in several notable Irish churches. The architect James Edward Rogers specified Milverton stone for the construction of Holmpatrick Parish Church in Skerries (consecrated 1868) and St Mary’s Church in Howth (1866). The same stone also features in Kenure Church, Rush, and other 19th‑century ecclesiastical buildings across the country. This historic link adds an architectural dimension to the quarry’s industrial heritage.

Geological wonders

Milverton Quarry is a valuable geological site. The limestone exposed here dates to the Carboniferous period (approximately 340 million years ago) and has yielded a diverse fossil assemblage, including brachiopods, bryozoans, crinoids, bivalves, gastropods and a range of micro‑fossils such as foraminifera and cyanobacteria. For rock‑hounds and palaeontology enthusiasts, the quarry offers a rare chance to see these ancient marine organisms in situ.

Scenic highlights

The most photographed feature is the turquoise pool that fills the quarry’s lower basin. Its vivid hue is a result of mineral‑rich water reflecting the limestone walls, not toxicity – the presence of otters, kingfishers and a thriving population of peregrine falcons confirms a healthy ecosystem. Bird‑watchers can often spot peregrines nesting on the sheer cliff faces, while otters and kingfishers frequent the water’s edge.

Walking the site

A short, informal trail runs along the quarry’s rim, offering panoramic views of the cliffs and the sea beyond. While the quarry is not a formal visitor centre, the path is accessible from the Skerries coastal walk. Keep an eye out for the remnants of the lime‑kilns, which are still visible and provide a tangible link to the site’s industrial past.

Environmental restoration and waste recovery

Roadstone Dublin Ltd holds an EPA licence for an inert‑waste recovery facility at Milverton. The operation back‑fills the exhausted quarry void with clean construction and demolition soil and stone, restoring the land for agricultural use and protecting the underlying groundwater. The facility accepts inert material weekdays 07:00‑18:00 and Saturdays 07:00‑13:00, with trucks passing through a wheel‑wash and weigh‑bridge before entering the site. Ongoing environmental monitoring covers noise, dust, surface water and groundwater quality.

Practical Information

Milverton Quarries are not a ticketed attraction; entry is free, but the site is privately owned and remains an active extraction area. There are no formal opening hours – visitors can access the site at any time, though safety signage must be obeyed and fenced‑off areas avoided. Parking is available in the Skerries town car parks, notably the Harbour Road car park a few minutes’ walk from the quarry entrance.

Access: From Dublin city centre take the M1 northbound to the Skerries exit (approximately 45 km). Follow signs to Skerries town, then head east along the R127 coastal road toward the quarry. Public transport includes the Dublin‑Drogheda rail line; Skerries station is a short walk from the quarry’s entrance.

Seasonal notes: The quarry’s cliffs are most striking after rain, when the pool level rises and surrounding vegetation is lush. The site can be windy, so a wind‑breaker is advisable.

Safety: As the quarry is still active, some areas are fenced off. Stay clear of any machinery, and do not attempt to climb the sheer faces. The wildlife, especially the nesting peregrines, are protected; keep a respectful distance to avoid disturbance.
