Western Scheldt in the context of "Zeelandic Flanders"

Antwerp (/ˈæntwɜːrp/ ; Dutch: Antwerpen [ˈɑntʋɛrpə(n)] ; French: Anvers [ɑ̃vɛʁs] ) is a city and a municipality in the Flemish Region of Belgium. It is the capital and largest city of Antwerp Province, and the third-largest municipality in Belgium by area at 208.22 km (80.39 sq mi). With a population of 565,039, it is the most populous municipality in Belgium, and with a metropolitan population of over 1.2 million people, the country's second-largest metropolitan area after Brussels.

Flowing through Antwerp is the river Scheldt. Antwerp is linked to the North Sea by the river's Westerschelde estuary. It is about 40 km (25 mi) north of Brussels, and about 15 km (9 mi) south of the Dutch border. The Port of Antwerp is one of the biggest in the world, ranking second in Europe after Rotterdam and within the top 20 globally. The city is also known as the hub of the world's diamond trade. In 2020, the Globalization and World Cities Research Network rated Antwerp as a Gamma + (third level/top tier) Global City.

Walcheren (Dutch pronunciation: [ˈʋɑlxərə(n)] ) is a region and former island in the Dutch province of Zeeland at the mouth of the Scheldt estuary. It lies between the Eastern Scheldt in the north and the Western Scheldt in the south and is roughly the shape of a rhombus. The two sides facing the North Sea consist of dunes and the rest of its coastline is made up of dykes. Middelburg, the provincial capital, lies at Walcheren's centre. Vlissingen, 9 kilometres (5.6 mi) to the south, is the main harbour and the third municipality is Veere.

Originally, Walcheren was an island, but the Sloedam, constructed in 1871 for a railway, and poldering after World War II have connected it to the (former) island of Zuid-Beveland, which in turn was connected to the North Brabant mainland by the Kreekrakdam (Completed in 1867). The Veerse Gatdam, completed in 1961, has connected Walcheren to Noord-Beveland.

The Port of Ghent is the third busiest seaport in Belgium, located in Ghent, East Flanders in the Flemish Region. The first port of Ghent was situated at the river Scheldt and later on at the Leie. Since the Middle Ages Ghent has sought for a connection to the sea. In the 13th century via the Lieve canal to the Zwin near Damme, in the 16th century via the Sassevaart, in the 17th century via the Ghent–Bruges canal. Since the 19th century, the Ghent–Terneuzen Canal connects the port via the Western Scheldt to the North Sea. The port of Ghent is accessible by ships of the Panamax size, and in February 2015 the construction of a new lock at Terneuzen was announced, which will maintain near-parity with those of the Panama Canal expansion project.

Zuid-Beveland (Dutch: [ˈzœyd ˌbeːvəlɑnt] ; "South Beveland") is part of the province of Zeeland in the Netherlands north of the Western Scheldt and south of the Eastern Scheldt.
