Work has commenced on the removal of HMS Victory's three masts, bowsprit and rigging ahead of the "most comprehensive overhaul" of the vessel for two centuries.

The upper section of the masts from Lord Nelson's flagship at the Battle of Trafalgar are to be removed, catalogued and documented in order to assist "future restorers" of the ship. HMS Victory currently attracts 400,000 visitors to its home in Portsmouth Historic Dockyard each year, while still remaining on service for the Royal Navy.

A 10-year restoration programme is proposed for the vessel, while an interactive exhibition will open in the National Museum of the Royal Navy to chart the ship's history. Professor Dominic Tweddle, director general of the museum, said: "Preserving a wooden warship is a battle - a battle against nature, and, just as epic, in its way, as the Battle of Trafalgar. To be able to witness how that battle is fought will be a big draw for visitors.

"Both Victory and the museum will remain open to the public throughout the restoration work."
