About

Dumbarton Castle (Scottish Gaelic: Dùn Breatainn, pronounced [t̪unˈpɾʲɛʰt̪ɪɲ]; Welsh: Alt Clut) has the longest recorded history of any stronghold in Scotland. It sits on a volcanic plug of basalt known as Dumbarton Rock which is 240 feet (73 m) high and overlooks the Scottish town of Dumbarton.
