Mike,
It is clear that the seven marken point does not
exist anymore.
My information comes from an information sign near
the stone and an article in Waardeel #2-2005.
On the web there are many references to "zeven
marken", "zevenlandenpunt" and "7 markenpunt" etc
I don't know of a map of the seven marken
on the web.
But I do know this site that shows the borders of
municipalities around 1832.
Municipalities are not the same as "marken" but it
can be found that in 1832 six municipalities where connected at De
Kiel.
click zoek, kaart, toponiem
at the bottom of the screen type "de kiel", click
zoeken, toon kaart.
on the map the six municipalities are shown.
click for example on the "MP" logo to show
a detailed map.
Zoom in on the point and find that there used to be
a marker there ("paal").
Groeten en suc6
