The Binnenhof — the Inner Court — is the medieval heart of Dutch government and one of the most atmospheric parliamentary complexes in Europe. The complex of buildings around a central courtyard has housed the seats of government since the 13th century, and despite the formality of its function, it is remarkably accessible: you can walk freely into the courtyard and look at the buildings from the outside.
At the centre of the Binnenhof stands the Ridderzaal (Hall of Knights), a 13th-century Gothic great hall topped with turrets and stained glass. The Hofvijver — the ornamental lake reflecting the towers and the facade of the Mauritshuis — frames the complex on the east side and makes for one of the most photographed views in the Netherlands. The parliament buildings underwent extensive renovation in the 2010s and some sections require guided tours to visit, but the courtyard itself remains open to anyone who walks in from the street.
