Kessenich is a village in the Belgian province Limburg. It is a section of the municipality of Kinrooi, lying in the eastern end of the municipality.
Kessenich is the end of the Grensmaas, the part of the Meuse who forms a natural border with the Dutch province Limburg. This river separates Kessenich from Stevensweert. In the north lie the Dutch villages of Thorn, Ittervoort and Neeritter. In the south lies Maaseik. The region of Kessenich is dissected by several rivers: the Abeek, the Itterbeek and Witbeek on their way to the Meuse.
East of Kessenich is an area with several ponds, the Maasplassen. They were created by large-scale exploitation of gravel from 1949. The gravel layer with a thickness of up to 10 m, was deposited by the Meuse, which repeatedly moved to the east. In May 2008 ended the gravel mining and began the partial attenuation of the lakes. Now, some Maasplassen are equipped for recreation or nature.
Its name is derived from the Gallo-Roman Cassiniacum. Kessenich is also named as Kesnic (1102), Kasnech (1132), Casselin or Cassenic (1155), Kessenich (1219) and Cessenic (1224). Later, it's also identified on maps as Kessingen (1573) and Kesnick (1754). In Limburgish it's still called 'Kesing'.
Kessenich is the oldest of the five villages of Kinrooi. It was founded as a Celtic settlement, then close to the Meuse. That has been shifted to the east and left north of the village a bogged arm behind. This marsh, the Vijverbroek, made in the Middle age as redoubt. According to a legend had between Kessenich and Thorn drowned the village Vijvere. Now it is a unique area overgrown with alder and other tree and plant species.
