Westermarsch II was an independent municipality until the 1972 territorial reform in Lower Saxony and, as such, a member of the collective municipality (Samtgemeinde) of Leybucht in Lower Saxony. Today Westermarsch II is a village in the East Frisian borough of Norden with around 500 inhabitants (as at 12/2016). The village parish covers an area of 11.69 km². Curiously the main settlement of Westermarsch II is associated in public perception with the village of Norddeich, with which it has grown together. The boundary between the two runs down the middle of the road, Dörper Weg.
