Great city if you have time. But do visit the extraordinary "Memorial" museum which is a huge museum about war, not just World War II. Allow three hours.
The city of Caen was a cozy town with a history very coated with the actions of The Second World War. The people around were relaxed and even though they didnt understand a word English they wanted to help you and had patience.
We went to this city mainly to visit the Normandy Museum - which was excellent. This was a key site in the Battle of Normandy and only fitting that they erected a Peace Memorial and this museum to commemorate the conflict.
