The Prins-Alexanderpolder is NE of Rotterdam, 6 meters below sealevel,
the deepest lying polder in the Netherlands. It was part of the polderboard
Schieland, and shared between the municipalities of Rotterdam, Zevenhuizen,
Nieuwerkerk, and Capelle. It was planned to be renamed Prins-Alexanderstad,
in Rotterdam and Capelle, with 180.000 inhabitants; now it is a "deelgemeente"
of Rotterdam. It has no coat of arms.
