Dysart Harbour dates way back to the 14th century, and the history behind the location is a rich one. In the 17th century, the harbour grew extensively when an influx in exports of coal and salt to the Baltic regions was agreed. Dysart Harbour is the filming location which became known as Le Havre in the series.
The French Harbour is first seen in the first episode of Season 2 when Jamie and Claire arrive. Upon their arrival, they meet the shows newly introduced villain Comte St. Germain. Although Claire and Murtagh rescue Jamie from the clutches of Black Jack Randall to escape to Paris, none of the filming ever took place in France.
