Esther Bell. "Catalogue Raisonné of the Thaw Collection." Studying Nature: Oil Sketches from the Thaw Collection. Ed. Jennifer Tonkovich. New York, 2011, p. 141, no. 118, ill. (color), calls it "River Landscape with Castle Ruins" and dates it to the 1820s.
Another study by Rottmann of these same ruins, Campagna—Tower in the collection of the Martin von Wagner-Museum, Würzburg, has been dated on a stylistic basis to the winter of 1826–27 (see Erika Bierhaus-Rödiger, Carl Rottmann 1797–1850: Monographie und kritischer Werkkatalog, Munich, 1978, pp. 190–91, no. 97, ill.).
