The City of the Sea by Jerome K. Jerome — Read

They say, the chroniclers who have written the history of that low-lying, wind-swept coast, that years ago the foam fringe of the ocean lay further to the east; so that where now the North Sea creeps among the treacherous sand-reefs, it was once dry land. In those days, between the Abbey and the sea, there stood a town of seven towers and four rich churches, surrounded by a wall of twelve stones' thickness, making it, as men reckoned then, a place of strength and much import; and the monks, glancing their eyes downward from the Abbey garden on the hill, saw beneath their feet its narrow streets, gay with the ever passing of rich merchandise, saw its many wharves and water-ways, ever noisy with the babel of strange tongues, saw its many painted masts, wagging their grave heads above the dormer roofs and quaintly-carved oak gables.

Thus the town prospered till there came a night when it did evil in the sight of God and man. Those were troublous times to Saxon dwellers by the sea, for the Danish water-rats swarmed round each river mouth, scenting treasure from afar; and by none was the white flash of their sharp, strong teeth more often seen than by the men of Eastern Anglia, and by none in Eastern Anglia more often than by the watchers on the walls of the town of seven towers that once stood upon the dry land, but which now lies twenty fathom deep below the waters. Many a bloody fight raged now without and now within its wall of twelve stones' thickness. Many a groan of dying man, many a shriek of murdered woman, many a wail of mangled child, knocked at the Abbey door upon its way to Heaven, calling the trembling-monks from their beds, to pray for the souls that were passing by.
