THIS GREAT HARBOUR (ORIGIN)

Known by mariners since Viking times as a safe anchorage in notoriously savage waters, Scapa Flow is the seaway that runs between Orkney and the island of Hoy. As the northern base of the Royal Navy and Allied fleets in both world wars, it witnessed some of the most seminal events in modern naval history. Here is the ultimate history of this remarkable place: both its military story and the impact war had on its community as their remote archipelago was transformed into the hub of Britain’s naval war machine.
