What is "westerkwartier"

The Westerkwartier is a historical region in the Dutch province of Groningen, at the border with the province of Friesland. In the past the area was part of the historical region of Frisia. The Frisian language is still spoken in the western parts of the area (the villages Marum, De Wilp and Opende). In the rest of the Westerkwartier, "Westerkertiersk", a local variant of Low Saxon, is spoken.

The biggest town in the Westerkwartier is Leek.
