Bog Mine

Mining History Feature

Background

Bog lead mine was worked on and off from before 1739 until 1924.

The mine was one of the first to install a Boulton & Watt engine for pumping. In 1838 a beam pumping engine (called 'Queen Victoria') with a 70" diameter cylinder and built by the Coalbrookdale Company was installed here - the biggest engine in the area. The foundations of the beam pumping engine house beside Engine shaft were excavated when the shaft was capped and remain to mark the site.

 

Bog School, now the Bog visitor centre

Although the area looks quite bleak today, there was once a thriving community here with dozens of houses and cottages mixed in with the mine buildings.

Today, only a handfull of buildings survive. The gas-lit Victorian school is now the Bog Visitor Centre (which is open daily through-out the summer) and the former public house - The Miner's Arms, is now a holiday cottage.

Bog Miner's Institute in the 1980s

The corrugated iron clad Miner's Institute building was demolished in the 1980s, only the lower part, it's Stiperstone Quartzite walls, with interpretation boards survive today. In it's heyday it was a popular location for dances and community events.

Near the present Car Park is the "Somme Tunnel", a 123 metre long level driven by Shropshire Mines Ltd., (c1917), to provide work for unemployed miners. The tunnel is still intact, but is home to rare bats, so has been gated to protect them.

Gated entrance to the Somme tunnel

West of Engine shaft the embankment of a tramway from Ramsden shaft crosses an overgrown reservoir (built in 1872 to store water for ore dressing) and ends just behind the remains of the Miner's Institute, at the site of the 1920s aerial ropeway terminus.

The ropeway took the output from the mine to Minsterley (over 5 miles away). Author Malcolm Saville based several of his novels in the Stiperstones area and the ropeway features in the book "Seven White Gates".

Bog magazine

The best survival is the magazine where explosives such as gunpowder and fuses were stored until needed underground.

At the top of the site one of several reservoirs that once supplied water to the mine still survives and is now an ideal place for spotting butterflies, dragonflies and other insects.

Bunting's shaft was near here, roughly where the concrete blocks are today. The wooden headframe over this shaft survived until the late 1960s.
