Royal Sphinx was a Dutch company in Maastricht that initially produced mainly pottery and later sanitary ware, among other things. It was a Dutch company founded by Petrus Regout in Maastricht in 1834. It was the first large-scale mechanized factory in the Netherlands and is considered the cradle of the industrial revolution in the Netherlands.
At Regout's death in 1878, it employed about 2,500 workers. The company was initially known as a producer of cut crystal, glassware, crockery and other household pottery; later mainly tiles and sanitary ware, such as sinks and toilet bowls. After the death of the founder (1878), the company was known as C.V. Petrus Regout & Co., and after the death of Pierre Regout from January 1, 1898, as N.V. Kristal-, Glas- en Aardewerkfabrieken De Sphinx, v/h Petrus Regout en Co., referred to simply as "The Sphinx" in the walk.
The factory ceased to exist in 2009, although the "Sphinx" brand name has continued to be held by Switzerland's Geberit through 2019. Sphinx Tiles, which split off in 1997, has also no longer had production facilities in Maastricht since 2008. The Sphinx and the closely associated Regout family have left many traces in Maastricht and the surrounding area.
