On the north-eastern coast of Zealand, about two miles from Gilleleie, is situate the village of Sjoeberg, where the spade and the ploughshare occasionally strike against the foundations of ancient buildings, and traces yet remain of the paved streets of towns, the names of which are no longer known, and over which the corn now grows or the cattle graze. Towards the close of the thirteenth century there was still standing a small town, built on the ruins of the ancient Sjoeberg. On a hill, surrounded by the water-reeds of the now nearly dried-up lake, fragments of walls of hewn free-stone lie buried in the earth, and mark the site of the strong and well fortified castle, which in the thirteenth and fourteenth centuries served as a place of confinement for state prisoners of importance. The spot on which the castle stood was then entirely surrounded by the lake, which thus formed a natural fastness, rendering artificial moats superfluous. The castle was surrounded by ramparts. It was built of massive free-stone, and had a strong square tower, in which the most dangerous state prisoners were confined. The air was close and bad in the subterranean dungeon of the tower, where no ray of light could enter; but the upper dungeon, at the height of thirty-six feet from the ground, admitted light and air through a small round grated window. In this upper prison, towards the close of the year 1295, was still confined one of the chief accomplices in Marsk[1] Stig's conspiracy[2], the turbulent and imperious Archbishop Iens Grand. He had been imprisoned here during the minority of Eric Menved, as an accomplice in the murder of Eric Glipping, and as the protector of the outlawed regicides.
