Saint-Germain-en-Laye (pronounced [sɛ̃.ʒɛʁ.mɛ̃.ɑ̃.lɛ]) is a French commune situated 19 km to the west of Paris in the département des Yvelines in the Île-de-France region. Since 1 January 2019 it has held the status of commune nouvelle following the absorption on that date of the commune of Fourqueux. The history of the town of Saint-Germain-en-Laye has long been linked to the presence of the château, which was a regular residence of the kings of France, though its importance diminished as a result of Louis XIV's move to Versailles, and to the forest, a former royal hunting ground.
