Here Turner has drawn a series of six views of Koblenz, taken from a variety of different perspectives on the Moselle and Rhine Rivers. The imposing Ehrenbreitstein fortress is prominent in all of the sketches; while the view of Koblenz with the Moselle Bridge also incorporates the twin towers of the Basilica of St Castor and those of the Liebfrauenkirche which are decorated with elaborate onion cupolas.
