Starting on Wednesday 6 August, the story of the Endurance will be celebrated with two days of talks and discussions led by renowned polar experts. These will focus on the expedition and its members, but also on how their sense of enterprise and discovery can inspire present and future generations.

Sir Ernest’s granddaughter, the Hon Alexandra Shackleton, will unveil two plaques to commemorate the occasion, the first at the Duke of Cornwall Hotel, and the second at Clyde Quay in Millbay, from where the Endurance set sail.

That departure from Plymouth will also be recreated at noon on Friday 8 August with an historic sailing ship, supplied by Cornish company Square Sail, leaving Millbay and heading out into Plymouth Sound.

Millbay’s lead developer English Cities Fund (ECf) has made Clyde Quay available for the re-enactment and it is hoped the plaque being unveiled there will become a permanent feature in the final regeneration of the area.

A replica of the tiny open boat in which Sir Ernest embarked on the 800-mile rescue mission from Antarctica, built for the 2013 Shackleton Epic Expedition, will also be in Plymouth for celebrations to mark his epic expedition.

Shackleton 100 Plymouth is being organised by the Devon and Cornwall Polar Society in partnership with University of Plymouth, Plymouth City Council, the Duke of Cornwall Hotel, Sutton Harbour Holdings, the English Cities Fund, Muse Developments and Associated British Ports. The event is also sponsored by Arcturus Expeditions, the James Caird Society, South Georgia Association, the Antarctic Heritage Trust and the Heritage Lottery Fund.
