Map of Breslau (Wrocław) in about 1807, showing also the fortifications as they stood before the siege of 1806, and which had been destroyed shortly after. Engraved by Friedrich Gottlob Endler. 
<p>The north direction of this map is skewed by about 30° anti-clockwise from the vertical line, so that the latter shows north-north-east.
