HMS Victory, Admiral Lord Nelson's flagship at the Battle of Trafalgar in 1805, is in the midst of a 12 year refit which managers say is the second-largest heritage restoration project in Europe after Notre Dame Cathedral. The 45 million pound (53 million euro) works have already seen many of the ribs of the ship - known as futtocks - removed, due to water entering and causing rotting over the years and attracting deathwatch beetles. Visitors can still look round the ship at its dry dock in Portsmouth, UK, with project manager Simon Williams saying the chance to see Victory in its stripped-back state is "a once in a lifetime opportunity."
