Here Turner depicts the town of Oberlahnstein situated in the foothills of the Westerwald and Taunus and at the confluence of the Lahn and Rhine rivers, approximately four miles south of Koblenz. Owing to their strategic importance on the Rhine, Oberlahnstein and Niederlahnstei (Lower and Upper Lahnstein) were heavily fortified, dominated by Lahneck and Martinsburg Castles and the Schloss Stolzenfels. It is the Burg Lahneck and the tower of the Martinsburg which Turner represents in this sketch, the former in the distance and the latter in the foreground. The artist has also inscribed ‘Laneck’ at the top right of the drawing.
