Photos: Italian ship Luigi Durand de la Penne docks at Canary Wharf
The huge Italian naval ship, over 147 metres long, made its way through the dock at West india Quay at around 11am and then, after some maneuvering around South Quay, docked at just after midday.
She caught the attention of visitors and workers to Canary Wharf, who will have the opportunity to take a closer look with organised tours onboard throughout the weekend.
Luigi Durand is one of the biggest ships in the Italian Navy and hosts more than 250 crew members and 90 cadets.
It is currently on a summer campaign to train the academy cadets, who are completing their first sailing experience on a warship.
She was helped into the docks by tug Svitzer Laceby.
The ship is on a training campaign which began from the Italian port of Livorno on July 14. After London it is heading to Malaga to carry out exercises with Spanish and French naval helicopters.
