[Illustration: THE DUNES. A Stormy Evening.]
The wild storms of the tenth, eleventh, and twelfth centuries changed the aspect of the coast of Flanders. Nieuport rose in consequence of one of these convulsions of Nature, when the inhabitants of Lombaerdzyde, which was then a seaport, were driven by the tempests to the inland village of Santhoven, the name of which they changed to 'Neoportus'--the new harbour. This was in the beginning of the twelfth century, and thenceforth the struggle against the waves went on incessantly. Lands were granted by Thierry d'Alsace on condition that the owner should construct dykes, and Baldwin of Constantinople appointed guardians of the shore, charged with the duty of watching the sea and constructing defensive works. But the struggle was carried on under the utmost difficulties. In the twelfth century the sea burst in with resistless force upon the low-lying ground, washing away the dunes and swallowing up whole towns. The inroads of the waves, the heavy rains, and the earthquakes, made life so unendurable that there were thousands who left their homes and emigrated to Germany.
Later, in the thirteenth century, there was a catastrophe of appalling dimensions, long known as the 'Great Storm,' when 40,000 Flemish men and women perished. This was the same tempest which overran the Dutch coast, and formed the Zuyder Zee, those 1,400 square miles of water which the Dutch are about to reclaim and form again into dry land. In the following century the town of Scarphout, in West Flanders, was overwhelmed, and the inhabitants built a new town for themselves on higher ground, and called it Blankenberghe, which is now one of the most important watering-places on the coast.
Ever since those days this constant warfare against the storms has continued, and the sea appears to be bridled; but anyone who has watched the North Sea at high tide on a stormy day beating on the shores of Flanders, and observed how the dunes yield to the pressure of the wind and waves, and crumble away before his eyes, must come to the conclusion that the peril of the ocean is not yet averted, and can understand the meaning of the great modern works, the _digues de mer_, or sea-fronts, as they would be called in England, which are being gradually constructed at such immense cost all along the coast.
