Kemnay Quarry

Overview

Kemnay, opened in 1858 by the Aberdeen quarrymaster John Fyfe, grew into one of Scotland's great granite quarries — its stone built the Forth Bridge, London's Thames Embankment and Aberdeen's own Marischal College, reputedly the second-largest granite building in the world.

History

Kemnay Quarry was opened in 1858 by John Fyfe, initially to supply stone for the Alford Valley Railway's bridge construction, and rapidly grew into a major industrial employer in what had been a small rural community: by 1881 the quarry employed 480 men and 26 boys, with Fyfe building tenement housing for the workforce arriving to fill the jobs. Fyfe proved an energetic innovator, developing the 'blondin' aerial ropeway system that went on to be used at deep-pit quarries across Britain, and equipping the site with its own smiddy of sixteen forges and a joiners' workshop for dressing stone. Kemnay's distinctive light grey, sparkling muscovite-biotite granite was used in major structures across Britain, including the Forth Bridge, the Thames Embankment in London and the Cenotaph, and, closer to home, Aberdeen's Marischal College — reputedly the second-largest granite building in the world — and the city's Municipal Buildings. Large-scale quarrying continued until around 1959, when extraction of dimension stone ceased; the site has continued in use since for aggregate and walling-stone production, today marketed as 'Fyfestone', under later ownership.

Geology

The quarry worked light grey, muscovite-biotite granite of the Kemnay pluton, part of the Caledonian granite suite intruded into the surrounding metamorphic rocks of north-east Scotland.

Workings

Fyfe's 'blondin' aerial ropeway system, developed at Kemnay, allowed stone to be lifted directly out of the deepening quarry pit rather than hauled up ramps, and was subsequently adopted at deep quarries across Britain; the site also had its own smiddy with sixteen forges and a joiners' workshop for dressing stone.

Closure

Large-scale extraction of dimension stone ceased around 1959, though the site has remained in continuous use since for aggregate and walling-stone production.

What remains

The site remains active as a producer of crushed aggregate and walling stone, marketed as 'Fyfestone', under ownership that has changed since Fyfe's day; it is no longer worked for large dimension stone.

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.
