With regards to South Limburg this deals with its hilly landscape, especially in the Heuvelland region, sunken lanes, an abundance of castles, and the regional language Limburgish spoken by a significant part of the population alongside Dutch.
The region also contains the highest point above sea level in mainland Netherlands, the Vaalserberg being 322.5 metres (1,058 ft) above sea level (the highest point of the entire country is in the Caribbean Netherlands' island of Saba, namely Mount Scenery being 887 metres (2,910 ft) above sea level).
The region South Limburg in addition, although extended a little further north to Roermond, forms a constituent part of the Euroregion Meuse-Rhine.
The estate region Maastricht-Meerssen (Dutch: Landgoederenzone Maastricht - Meerssen) is the name for an area stretching from the northeastern parts of Maastricht to the south of Meerssen that is characterised by a large number of estates.
A majority of said estates have been built (or renovated) by the 19th century Maastrichtian industrialist Petrus Regout and his descendants.
