Vlissingen, harbour town on the Westerschelde, has the longest sea promenade in the Netherlands, here you can almost touch the passing sea ships. Under the Spanish, new defences were built around the town, the Keizersbolwerk was built between 1548 and 1552, which can still be seen today next to today’s Koopmanshaven. Dutch naval hero Michiel de Ruyter keeps an eye here, he worked his way up to become commander-in-chief of the Dutch fleet and won many sea battles. With the beach and sea within easy reach, Vlissingen is a lovely place to take in the fresh sea air.
