This parish of Polwarth is, in area, the second smallest in Berwickshire. It has always been an agricultural area, though in 1866 it was reported that approximately one third of the total was hilly and covered in heath. The Marchmont estate occupies a substantial part of the parish and estate workers accounted for many of the residents of Polwarth.
The exact population prior to the 18th century is unknown though, in 1811, it is believed that Polwarth was home to over 300 people most of whom relied upon the estate for their living. The village must have been of importance because it hosted an annual fair, St Mungo’s Fair, attended by people from all over the area. It has even been said that the Scottish king, James V, attended the fair one year.
Technically, Polwarth was the County Town of Berwickshire, but only for one night! At the end of the 19th century, the County Town changed from Greenlaw to Duns and the coach carrying the documents investing that status made an overnight stop at Polwarth.
As happened with many great estates, the needs of the First World War began a decline in the number of people employed at Marchmont. A decline which progressed with the coming of mechanised farming and the Second World War. In addition, improved transport meant individual villages no longer needed to be self-sufficient for trades and services. By the early 21st century, the population of the parish was in single figures and, though some new houses have been built, it is not expected that numbers will rise enough to merit the designation of ‘village’
