South Limburg (Dutch: Zuid-Limburg, Limburgish: Zuud-Limburg) is both a COROP (statistical) region as well as a landstreek (area) of the Netherlands located in the province of Limburg. The Dutch term landstreek, literally translated "land area/region", means that the area is not an administrative region but an area that displays cohesion with regard to culture and landscape. 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 322.5m (1,058.1feet) above sea level (the highest point of the entire country is in the Caribbean Netherlands' island of Saba, namely Mount Scenery being 887m (2,910feet) 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. The area is crossed by three rivers (namely the Meuse, Geul and Kanjel). A majority of said estates have been built (or renovated) by the 19th century Maastrichtian industrialist Petrus Regout and his descendants. Challenges to transforming the entire region into a recreational area are posed by the crossing of the A2 motorway and various railways through the area as well as the industrial area of Beatrixhaven.
The region spans six neighbourhoods of Maastricht namely:
