Well, not exactly an obelisk, but this is the centre of the Dutch
triangulation grid as used by the cadaster and the topographical
service: http://www.vvv-amersfoort.com/kunst/architectuur/histor1.htm

So you could say it is the centre of the Netherlands (although the
geographical centre is somewhere else. I vaguely remember it to be
somewhere near Lunteren). It is the starting point of all surveying.

It used to be X=0 m, Y=0 m. But then they thought it would be better
to have only positive co-ordinates in the Netherlands, so they moved
the point to the south-west. The grid stayed the same, but the tower
nowadays has the co-ordinates X=155000 m, Y=463000 m.

I visited the tower (Onze Lieve Vrouwetoren) in the city of
Amersfoort last year. As I remember, the X and Y axis are depicted on
the ground and radiate from the tower.
