Claim: Rotterdam–The Hague metropolitan area has the largest European port within its borders and is a part of the larger urban area called Randstad—a megalopolis in the central-western Netherlands which contains the Port of Rotterdam, Port of Amsterdam, and Amsterdam Airport Schiphol.
Evidence: The Rotterdam–The Hague metropolitan area (Dutch: Metropoolregio Rotterdam Den Haag) is a metropolitan area encompassing the cities of Rotterdam and The Hague as well as 21 other municipalities. The largest European port and many international organizations reside within its borders. The area is also part of the larger urban area called Randstad. The Randstad (Dutch pronunciation: [ˈrɑntstɑt) is a megalopolis in the central-western Netherlands consisting primarily of the four largest Dutch cities (Amsterdam, Rotterdam, The Hague and Utrecht) and their surrounding areas. Among other things, it contains the Port of Rotterdam (the busiest seaport in Europe and until 2004 also the world's busiest seaport), the Port of Amsterdam (Europe's fifth busiest seaport), and Amsterdam Airport Schiphol (third-busiest European airport).
