Groningen
Groningen in the north east of the Netherlands consists of two historical parts: the (Saxon) city of Groningen and the (Frisian) Ommelanden, the rural areas of the province. The flag, adopted 17 February 1950, reflects this: Green and white are the city's colours, placed in the centre for the central role of the capital. Red, white and blue are derived from the arms and flag of the Ommelanden, similar to the Frisian flag.
