Boundary post
Boundary posts that mark the old border between the County of Holland and the Duchy of Brabant from the 13th century.
The village of ‘s-Gravenmoer still has the small dykes which for seven centuries formed the border between the County of Holland and the Duchy of Brabant. To make this old border visible again, nine oak boundary posts bearing the coats of arms of Holland and Brabant were installed in 2010.
