Laurencekirk
Laurencekirk is a town in the historical area of Kincardineshire, Scotland, simply off the A90 Dundee to Aberdeen highway, which bypassed it in 1985. It is provided as part of Aberdeenshire. It is the biggest settlement in the Howe o' the Mearns area as well as houses the regional high school; Mearns Academy, which was granted the Charter Mark in 2003. Its old name was Conveth, an anglification of the Gaelic Coinmheadh, referring to a commitment to provide complimentary food and board to passing troops. Laurencekirk remains in the valley between capital of Garvock as well as the Cairn O' Mount. The popular landmark of the Johnston Tower can be seen on the top of the Garvock. Laurencekirk was, in the past, known for making snuff boxes with an unique type of impermeable hinge (known as a "Laurencekirk hinge") created by James Sandy. Laurencekirk Golf Club (currently inoperative) first showed up in the early 1900s. The club shut at the time of WW2. Lewis Grassic Gibbon composed much concerning The Mearns and the surrounding area in his book Sunset Song. A homage centre can be checked out at Arbuthnott a few miles from Laurencekirk. Fred Urquhart worked with the land at Laurencekirk in the Second World War, and also his narratives make use of his observations of rural life below.
