Architectural Geology
There are many buildings in Dumfries made from sandstone of the local Locharbriggs quarry.
The quarry is situated off the A701 on the north of Dumfries at Locharbriggs close to the nearby aggregates quarry. This dimension stone quarry is a large quarry. Quarry working at Lochabriggs dates from the 18th century, and the quarry has been worked continuously since 1890.
There are good reserves of stone that can be extracted at several locations. On average the stone is available at depths of 1m on bed although some larger blocks are obtainable. The average length of a block is 1.5m but 2.6m blocks can be obtained.
Locharbriggs is from the New Red Sandstone of the Permian age. It is a medium-grained stone ranging in colour from dull red to pink. It is the sandstone used in the Queen Alexandra Bridge in Sunderland, the Manchester International Convention Centre and the base of the Statue of Liberty.
