Wellesley Colliery

Overview

Sunk on the Firth of Forth shore as Denbeath in the 1880s and renamed Wellesley when the Wemyss Coal Company rebuilt it in 1905, this was for decades one of Scotland's largest collieries — working seams out under the sea, feeding what was in 1938 the biggest coal washery in Europe, and giving Scotland its first pithead baths.

History

Bowman & Company sank the pit as Denbeath Colliery between 1883 and 1885, working the shallow seams close to the shore. The Wemyss Coal Company took it over in 1905, renamed it Wellesley and set about rebuilding it on a wholly different scale: a third shaft, elliptical in section, was added from 1907 and production came back on line in 1910, by which time the deep shaft had reached the Dysart Main seam at 261 fathoms. The sinkers used an unusual method to get there, running levels from the adjoining shafts at four separate horizons and cutting upwards from each, which took the 150-fathom section in about fifteen months.

The company built pithead baths here in 1915 — the first in Scotland and the second in Britain — and extended them with Miners' Welfare Fund money in 1938. By then Wellesley's Baum-type central washery was the largest in Europe, and it washed not only Wellesley's coal but that of the Randolph, Lochhead, Frances and Michael collieries too. The pit passed to the National Coal Board in 1947 and stood second only to Michael in Scottish annual output. Its workforce peaked at 2,603 in 1957.

Geology

The colliery worked house and steam coals in the Fife coalfield — the Barncraig, Chemiss, Dysart Main, Coxtool, Bowhouse and Brankston seams among them — with the deeper workings reaching out beneath the Firth of Forth.

Workings

Two circular shafts, both 481 m deep, sunk in 1883 and 1885, with a third elliptical shaft added in 1907. In 1938 two steam winders were at work, fed by fourteen Lancashire boilers. In 1948 the colliery raised 1,700 tons a day, 440,300 tons in the year, with 1,543 employed.

Closure

Wellesley closed in July 1967, during the period of major closures that also took Minto two months earlier, and just two months before the fire that ended neighbouring Michael Colliery. The shafts were still being used for pumping in 1970 and the mine was formally abandoned in 1972.

What remains

Nothing of the colliery survives above ground. After closure the site carried a major oil production platform construction yard, built by Redpath Dorman Long and its successors, and it now forms part of Fife Energy Park at Methil Docks, owned by Scottish Enterprise. Fife Council planning papers of August 2021 record the ground as vacant, latterly used for parking and as a marshalling yard.

No colliery structures survive. The practice of tipping colliery waste on the coast, together with subsidence, altered the shoreline here — silting the harbour and eroding the beach — and that reshaped foreshore is the most substantial physical trace the pit left.

Redevelopment

The site has been through two industrial lives since the pit: an offshore platform yard, and now Fife Energy Park, a development area on the Methil waterfront. The colliery's most durable physical legacy is not a building but the shoreline itself, reshaped by decades of tipping colliery waste on the coast and by subsidence, which silted the harbour and eroded the beach.

What's uncertain

Points where sources disagree or the record could not be settled; both accounts are kept. All open questions in the archive.

• Sources differ on the workforce: Canmore records an average of 1,908 with a peak of 2,603 in 1957, while the Northern Mine Research Society gives an average across the pit's life of 1,208 underground and 342 on the surface. (disputed) ^1,2
• Methil Docks were fed directly from the colliery and its coal-washing plant at Denbeath; after the 1907 enlargement the works employed over 1,600 people and handled more than 3,500 tons a day. (uncertain) ⁵
