Overview

A Midlothian pit owned by the Shotts Iron Company, permanently closed within months of an underground fire on 5 September 1889 that killed 63 of the 70 men and boys working there that day — one of Scotland's worst mining disasters.

History

Mauricewood Colliery, near Auchendinny outside Penicuik, was owned by the Shotts Iron Company Ltd. Its main shaft reached 239 metres. On 5 September 1889, at around noon, sections of the wooden lining of a ventilation shaft caught fire; smoke and flame spread into the return airway and penetrated the working sections below, cutting off escape by the main shaft. Of the 70 men and boys underground that day, 63 died and only 7 survived — one of the worst mining disasters in Scottish history (see Disasters, below). The pit never reopened for production. Its closure caused major losses to the two local railway lines that had served it, the Penicuik Railway and the Edinburgh, Loanhead and Roslin Railway. A memorial to the disaster's dead was erected on the site's centenary in 1989, standing just off Mauricewood Road, and the tragedy later inspired Dorothy Alexander's 2016 novel 'The Mauricewood Devils', which explores the experience of the disaster's widows and families.

Workings

A single main shaft, 239 metres deep, with a separate ventilation shaft whose wooden lining caught fire in 1889.

Closure

What remains

No specific present-day surface condition was established from the sources checked for this pass.

A memorial to the 1889 disaster's dead, erected on its centenary in 1989, stands just off Mauricewood Road.

Abandoned workings can be dangerous — unstable ground, uncapped shafts, flooding and bad air are common even where a site looks safe from the surface. This entry describes history and general location only; it is not an access guide.
