Land van Heusden en Altena

It resembles comparable landscapes in the latter one, like e.g. the Alblasserwaard, which is situated just north of the region.

It is enclosed by the rivers Boven Merwede (north), Afgedamde Maas (east) and Oude Maasje/Bergse Maas (south), and by the region of De Biesbosch, including De Biesbosch National Park (west).

Werkendam is the largest town, and Woudrichem the historical centre of the island.

The former municipalities of Werkendam and Woudrichem formed the region of the Land van Altena, while the former municipality of Aalburg formed the region of the Land van Heusden.

Unlike most parts of North Brabant, the Land of Heusden and Altena has a strong Protestant (Calvinist) character.
