Vliedberg
In the Netherlands, a Vliedberg is an artificial hill that was created in the early Middle Ages as an escape hill during floods . You can find Vliedberge in the Dutch province of Zeeland , there especially on the Walcheren peninsula .
Vliedberge are similar to terps , such as those found in Germany, for example on the Halligen . In contrast to the terps, however, they were much smaller and not intended to accommodate entire settlements. With the systematic embankment of the Dutch coast, the Vliedberge lost their function as a refuge during floods . Many Vliedberge were then redesigned to lookout points for observation posts, from which approaching enemies could be recognized early. For this purpose, the originally flat, only a few meters high hills were piled up to a height of sometimes over 10 meters and equipped with watchtowers. While these watchtowers are no longer preserved today, you can still find many Vliedberge , especially on Walcheren . They are under monument protection.
