The county of Dumbartonshire is located in southwestern Scotland, bounded on the north by Perthshire, on the east by Stirlingshire, on the southeast by Lanarkshire, on the south by the Clyde estuary and on the west by Loch Long and Argyllshire. The area is about 270 square miles. The scenery is some of the finest in Scotland, with numerous lochs, wild glens, and mountain highest. The highest points are about three thousand feet above sea level. In the south are the Kilpatrick Hills.
Perhaps the most famous glen in the county is Glen Fruin, called the "Glen O'Weeping" because of an ancient and terrible battle here between the Macgregors and the Colquhouns. The largest lake is Loch Lomond.
Dumbarton is the county town. Helensburgh is the chief port on the Clyde. There are various Roman remains in the county, including portions of the ancient walls of Antonius.
