The Lammermuir Hills, usually simply called the Lammermuirs (An Lomair Mor in Gaelic), form a natural boundary between East Lothian and the Scottish Borders.
They span the areas of East Lothian Council and Scottish Borders Council, and they extend from Gala Water to St. Abb’s Head and offer a traditional site for sheep grazing. The hills are nowhere especially high, the highest points being Meikle Says Law at 535m (1,755ft) and the Lammer Law at 528m (1,732ft), but the steep gradients, exposure to the elements and a lack of natural passes combine to form a formidable barrier to communications between Edinburgh and the Borders.
The hills are crossed by only one major road (A68), which crosses the shoulder of Soutra Hill between Lauder and Pathhead, and is frequently closed by snow in Winter. The name Lammermuir literally means ‘lambs moor’ or ‘moorland of the lambs’ from the old English ‘lambra’ and ‘mor’.
White Castle was an Iron Age hill fort, settled by the ancestors of the Votadini tribe. Two ranges of hills in New Zealand, the Lammermoor Range and Lammerlaw Range are named after the Scottish hills and their second highest peak respectively.
There is a reservoir in the hills called Whiteadder Reservoir five miles southeast of Garvald. It was created in the 1960’s with the flooding ceremony in May 1968. It supplies East Lothian and Berwickshire, including Cockenzie Power Station and is fed by Whiteadder Water, the lowest tributary of the River Tweed.
