Simply exquisite, the Mauritshuis is The Hague’s finest art gallery. Its internationally famous collection of Dutch art is shoehorned into a charming mansion that dates back to 1641. Much of the interior you see today is original, and the silk wall coverings and monumental painted ceilings provide an ideal setting for a mesmerising range of 17th-century Dutch art. Highlights include portraits by Rubens, several stunning pieces by Rembrandt, and – perhaps most famous of all – three wonderful canvases by Vermeer, Girl with a Pearl Earring, Diana and her Nymphs and View of Delft. Whatever else you do while you’re in The Hague, don’t miss this.
