Britain at Low Tide S03E02 - Firth of Forth

Palaeobiologist Tori Herridge and her team investigate the coastline of Scotland, uncovering archaeological finds that have been left behind by the tide in the inner reaches of the Firth of Forth. Tori also uncovers the story behind a long-forgotten harbour that is regarded as the birthplace of the Scottish whisky industry. Plus, why a 16th-century entrepreneur decided to tunnel under the sea and how a 19th-century pier proved vital to the continuing success of cattle farmers across central Scotland.
