Kasteel Cortenbach (Cortenbach Castle) and its farmhouse are dating back to the 14th century. Remains of this original castle are the two round towers, which were built with a locally found stone. These towers probably were the corner towers of the outer bailey.

The current castle was built around the year 1713 as a mansion by the merchant “Herman Lamberts” from Aachen. He was lord of Cortenbach since 1682. In 1776 large parts of the castle were rebuilt again. In 1869 the last widow of the Dutch line of the “De Lamberts de Cortenbach” family died at the castle.

Kasteel Cortenbach is one of five castles in the village of Voerendaal. Since 1988 it is private property, housing the main office of a company; hence it is not open for public. The castle is a national monument.
