Royal Sphinx

Koninklijke Sphinx was a Dutch company in Maastricht that initially mainly produced earthenware and later sanitary ware. It was a Dutch company that was founded in Maastricht by Petrus Regout in 1834. It was the first large-scale mechanized factory in the Netherlands and is seen as the cradle of the industrial revolution in the Netherlands.

At the time of Regout's death in 1878, the company employed approximately 2,500 workers. The company was initially known as a producer of cut crystal, glassware, tableware and other household pottery; later mainly of tiles and sanitary ware, such as washbasins and toilet bowls. After the founder's death (1878), the company was known as CV Petrus Regout & Co., and after Pierre Regout's death from 1 January 1898 as NV Kristal-, Glas- en Aardewerkfabrieken De Sphinx, formerly Petrus Regout en Co., colloquially referred to as "De Sphinx".

The factory ceased to exist in 2009, although the brand name "Sphinx" was still used by the Swiss Geberit until 2019. Sphinx Tegels, which was spun off in 1997, has also had no production facilities in Maastricht since 2008. The Sphinx and the closely associated Regout family have left many traces in Maastricht and the surrounding area.
