Middelburg Middelburg Middelburg () is a city and municipality in the south-western Netherlands serving as the capital of the province of Zeeland. Situated on the central peninsula of the Zeeland province, "Midden-Zeeland" (consisting of former islands Walcheren, Noord-Beveland and Zuid-Beveland), it has a population of about 48,000.
