I continue strolling along the promenade behind the sandy beach and head towards the harbour and the former submarine bunker, which was built by the Nazis during the Second World War. ‘The last commander refused to give up until three days after the end of the war, waiting for the order from Admiral Dönitz, Commander-in-Chief of the Kriegsmarine, to surrender,’ says Günter, shaking his head. And how does it feel to be a German living here, in a city with such a past? ‘No problem!’ he says, which is remarkable considering that because of the bunker, the entire city was bombed by the Allies and 85% of it was destroyed. ‘But the inhabitants were warned by the Allies beforehand and moved to the surrounding area,’ says Günter. The reinforced concrete of the bunker, however, held up. Today, people are quite relaxed about this indestructible legacy: it now houses various museums and an event hall. A Tintin poster hangs in front of it, because the two were here together with Captain Haddock. Fans can hunt down the posters scattered throughout the city and enjoy them, because St-Nazaire is one of the few cities that appear in a Tintin comic. Understandably, they are proud of this.
I walk to the sea, where the waves crash onto the beach, more powerful than the lapping of the Loire that accompanied me, and think: Adieu, Loire! Bienvenue, Atlantique!
