Scottish Towns and Cities. Helensburgh.

Helensburgh (/ˈhɛlənzbərə/ HEL-ənz-bər-ə; Scottish Gaelic: Baile Eilidh) is a town on the north side of the Firth of Clyde in Scotland, situated at the mouth of the Gareloch. Historically in Dunbartonshire, it became part of Argyll and Bute following local government reorganisation in 1996.

History context (Prehistoric–1858)

Although it has long been known that there are some prehistoric remains in the Helensburgh area, recent fieldwork by the North Clyde Archaeological Society has uncovered more. However the oldest building in the town itself is Ardencaple Castle which was the ancestral home of Clan MacAulay, and the history of which may date back to the twelfth century. Today only one tower of this building remains, the rest having been demolished in 1957–59.
