It is located adjacent to the Binnenhof, the meeting place of the States General of the Netherlands; the entrance to the House of Representatives can be found on Plein 2. The Mauritshuis art museum is located on Plein 29.Het Plein was originally a garden, forming a part of the Binnenhof castle, residence of the Counts of Holland. It was used to grow vegetables for the court. The garden was surrounded by a ring of canals and intersected by ditches. As a town square, Het Plein was constructed in 1632 and was inspired by the Place des Vosges in Paris.
A statue of William the Silent, made by Dutch sculptor Lodewyk Royer, was installed in the centre of the square in 1848.
