Curious about the monument so I took a drive down the coast of Scheveningen using Google Maps and found it.
(Nice beach by the way )
Memorial of King William I
"The Gedenknaald in Scheveningen is a monument that commemorates the departure of Prince Willem V in 1795 and the arrival in Scheveningen of Willem I Frederik on 30 November 1813.
The initiative to erect a monument was taken in 1863 by King Willem III . His uncle Prince Frederik became chairman of a committee that the king set up to devise a national memorial dedicated to the restoration of Dutch independence.
The memorial needle was unveiled on August 24, 1865, the birthday of King Willem I. Prince Frederik gave a speech and alderman H. Baron Collot d'Escury , acting mayor, then received the monument on behalf of the municipality. The ceremony was also attended by Queen Sophia , Crown Prince Willem , Prince Alexander and Prince Hendrik .
The monument is a national monument . It was designed by architect Arend Roodenburg and made by stonemasons PJ Devillers & Co. In 2003 the monument was restored."
