Weymouth Harbour is one of the prettiest in the UK and it is easy to see why. There are colourful cottages, fine restaurants and inviting pubs dotted amongst Georgian architecture and interesting alleyways, leading to quaint shops (and more pubs!) All this and Tall Ships as well!
We also have several veteran boats from World War Two which were used in the Dunkirk evacuations (as seen in the movie). Part of the film shows the Harbour, right behind Aaran House. Weymouth Harbour was the embarcation point for 450,000 trooops during WW2.
