Kilwinning
Kilwinning is a town in North Ayrshire, Scotland. Positioned on the River Garnock, it is 21 miles north or Irvine and 21 miles south of Glasgow, with its neighbouring towns being the coastal towns of Stevenston to the west and Irvine to the south. It is regarded as 'The Crossroads of Ayreshire'. According to the 2011 Census, the town has a population of 16109, growing slightly from the 15908 inhabitants documented in the 2001 Census. Much of the development taking place in Kilwinning began in the 1960s. As a result of the Glasgow Overflow relocation process, brand-new estates were set up rapidly on surrounding farm land in order to accommodate the projected boost in population. The historic town centre is still pedestrian-friendly, and they are surrounded by the housing estates of Corsehill, The Blacklands, Woodwynd, Pennyburn, Whitehirst Park, and Woodside. Also, Kilwinning's Main Street has more recently been renovated as a project undertaken by the Irvine Bay Regeneration Company. Such regeneration led directly to a broad number of brand-new companies establishing shops in the town centre. The service and retail sectors are steadily growing in importance in the town, as the town's traditional association with coal mining, quarrying, iron-founding and fabric manufacture having entered into decline. Kilwinning is known for being home to the ruins of Eglinton Castle. Constructed between 1797 and 1802, the Gothic castellated style made it a structure of much magnificence. The Castle is remembered mainly as the location of the Eglinton Tournament of 1839, which served to drain the Eglinton family fortune.
