Inveruglas Castle, Dunbartonshire
Inveruglas, Loch Lomond
Inveruglas Castle is a ruined 16th century Z-planned tower house located on an island in Loch Lomond, and is said to have once been linked to the shore by a causeway.
This is the oldest stronghold of Clan MacFarlane before the chief was forced to abandon it after Oliver Cromwell's forces bombarded and then torched the castle in the mid seventeenth century.
You can get a glimpse of the castle from the Loch Lomond visitors centre.
