Lauder
The Royal Burgh of Lauder is a town in the Scottish Borders in the historical county of Berwickshire. On the Southern Upland Way, the burgh lies 27 miles south east of Edinburgh, on the western edge of the Lammermuir Hills. The current population of the town is around 1500, although it is quickly increasing as over 100 new houses are being developed on the southern side. This means that, at the start of the 21st century, the population is approaching what it was at the start of the 20th century ahead of the duration of depopulation over the last 100 years. Lauder is today highly directed by its distance to Edinburgh as it is now considered to be near enough for people to commute into the capital for work. The bus service to Edinburgh is dependable but sporadic. Noteworthy structures in the town today feature the Tolbooth or Town Hall, which predates 1598 when records reveal it being burnt by a party of Homes and Cranstouns led by Lord Home, in a dispute in between them and the Lauder family who were at the time sitting on the bench as hereditary baillies. On 18 July 1793, amid a serious and lengthy thunderstorm, a 'ball of fire struck the steeple above the Tollbooth, and did considerable damage'. Ongoing controversy in Lauder is the town's development, whether it is required or worthwhile, the location of a new primary school and how quickly one will be built, and the area and amount of wind farms on the surrounding hills. Additionally on the agenda is the discussion surrounding the formation of a brand-new health centre in the burgh.
