Perthshire (Siorrachd Pheairt), is a highland county located in central Scotland. And, along with Kinross, Aberdeenshire, Angus, Inverness, Argyll and Bute, Moray, Stirling and Isle of Arran, is one of eight areas with the Highland Council’s administration. A local administrative county between 1890 and 1975, Perthshire extends from Strathmore in the east, to the Pass of Drumochter in the north, Rannoch Moor and Ben Lui in the west, and Aberfoyle in the south. Perthshire offers a wide range of landscapes from agricultural straths to the high mountains of the southern Highlands giving it the descriptive name "big county”.
The Highland Council is the administrative body for much of the Highlands, with its administrative centre at Inverness. However, the Highlands also includes parts of the Perth and Kinross council areas.
Prior to the 1890s Perthshire's boundaries were irregular: the parishes of Culross and Tulliallan formed an exclave some miles away from the rest of the county, on the boundaries of Clackmannanshire and Fife; while the northern part of the parish of Logie formed an enclave of Stirlingshire within the county.

Coat of arms
The coat of arms of the County of Perth appears to have been granted for use on the colours and standards of the volunteer and militia units of the county raised at the end of the eighteenth century. The Earl of Kinnoull, a native of Perthshire, and commanding officer of the Perthshire Gentlemen and Yeomanry Cavalry, was also Lord Lyon King of Arms at the time, and he presented the arms to the county in 1800. The grant document was discovered in the Lyon Office in 1890, and forwarded to the newly formed Perth County Council. Image courtesty of Wikipedia.
The shield is very similar to the Scottish royal arms, reflecting that Perthshire was the home county of the House of Dunkeld and contains the former royal capital, Scone. Further royal references are made on the canton, which shows Scone Palace surmounted by the Crown of Scotland. The crest is a Highland soldier, reflecting that the famous Black Watch were formed in the county. The supporters are an eagle and a warhorse, the former from the arms of the city of Perth.
