Gottorp.

The ducal coat of arms and the arms of the city of Schleswig at the corners of an equilateral triangle draw our attention down to the little church of Hedeby in the foreground, and thus to the origin of Schleswig and the castle of Gottorp, namely the old commercial metropolis of Haithabu.
After its destruction in 1066, its place was taken by Schleswig. The moated castle, residence of the Dukes of Schleswig-Holstein-Gottorp, developed out of a fortress on the Danish frontier wall, the Danewerk (K). The view across the Schlei in cavalier perspective, with north at the top, shows the city overlooked by the tower of St Michael (C). The cathedral of St Peter (D) was begun in 1134 and completed in the 16th century.
To the right of it is the former collegiate church of the 13th-century Franciscan monastery, which was converted into a town hall (G) after the Reformation. At this time Schleswig had already lost its preeminent position in trade to Lübeck.

COMMENTARY BY BRAUN: "Long ago Schleswig was the capital of the whole territory of Cimbria, a big city and wealthy because of its important commercial activities, but now it has lost its former splendour because of the misfortune brought upon it by God. It has a harbour, which is ideally suited to trade. For formerly the trade goods were brought from the Netherlands, England, France and Spain to the Eider Estuary, and then on the Treene to Hollingstedt and from there very easily to Schleswig, and further over the Baltic Sea to the Kingdom of Denmark, to Norway, also Livonia, Russia, Prussia and other German provinces on the Belt."
