What is "warfhuizen"

Warfhuizen ( Gronings: Waarfhoezen) is a village in province of Groningen, located in the northern part of the Netherlands. It is part of the municipality of the Marne.

Warfhuizen consists of two man-made mounds, called wierden, designed to escape the floodwaters of the Wadden, which flooded the whole region several times a year before dykes had been coed. The smaller mound was originally raised to protect a separate village called Burum. The village church stands on the larger mound.
