The fort his ministers commissioned to guard the new harbour at Hugh Town was meant to be the most advanced piece of military engineering in England, an Italianate star fort with arrow-headed bastions and curved orillons that no English mason had ever built before. The work stopped in 1554, before the walls reached their full height. Only the south-western corner stands now, two squat bastions and a low curtain of granite, waiting for an army that never came. The name is wrong, too. The locals long credited the fort to Edward's father, the great wall-builder Henry VIII, and called the ruin Harry's Walls. The mistake stuck.
