Berkwickshire is a border and maritime county occupying the southeast tip of Scotland. It is bounded on the north and east by the North Sea, on the southeast by the Tweed and Northumberland in England, on the south by Roxburghshire, on the west by Midlothian, and on the northwest by East Lothian. It covers an area of 457 square miles.
The land is generally low and fertile in the south. In the northwest it rises into the Lammermuirs, the highest peak of which is Says Law at 1749 feet. In the western part along the Leader River are the Lauderdale Mountains. The coastline is bold and rocky, and the few harbors are much exposed. Principal rivers are the Tweed, which forms the boundary with England for 21 miles, as well as the Eye, Leader, Eden, Leet, Dye, and Black and White Adders.
Duns is the county town. Other large towns are Lauder, Eyemouth, and Coldstream.
