Dive beneath the River Hamble to uncover the secrets of Henry V's colossal flagship, the Grasse Dure - was it a naval marvel or a doomed giant?
Join our team of archaeologists and divers as they race against time to excavate what may be the remains of the Grasse Dure, the largest ship of the medieval world, lost for nearly 600 years. This documentary explores the ship's incredible history, from her ambitious construction and single ill-fated voyage to her mysterious end in the mud. Using cutting-edge sonar technology and hands-on underwater excavation, we reveal new insights into medieval shipbuilding, the sheer scale of materials used, and the challenges faced by Henry V's navy.
You'll discover how the Grasse Dure dwarfed her rivals, why her crew mutinied, and what life was like in the bustling royal shipyards of 15th-century England. Watch as the team battles poor visibility, tricky river conditions, and experimental equipment to uncover evidence hidden deep in the silt - from massive timber frames to ancient shipwrights' tool marks. Along the way, we piece together the story of Burzildon, the medieval port that supplied England’s war effort, and learn why the Grasse Dure marked both a high point and a technological dead end in naval design.
Whether you're fascinated by maritime archaeology, medieval history, or the untold stories beneath our rivers, this gripping investigation sheds new light on a forgotten giant of the seas.
