The Red Lands form a geographic region in southern and south-western Luxembourg.
[1] The Red Lands roughly correspond with the southern part of the canton of Esch-sur-Alzette, along the border with France.
Geologically, the Red Lands are sedimentary, mostly sandstones and conglomerates, formed in the Middle Jurassic epoch.
Throughout the period of industrial decline, the Red Lands have diversified into production of construction materials, engineering services, and chemical manufacturing.
The region is the most densely populated part of Luxembourg, with several of Luxembourg's largest towns and cities, including Bettembourg, Differdange, Dudelange, Esch-sur-Alzette, Kayl, and Schifflange, all of which have populations in excess of 7,000 people.
