A few Castellated mansions of more local inspiration, such as Hohenschwangau in Upper Bavaria, as reconstructed by J. D. Ohlmüller (1791-1839) in 1832-7, are closer in spirit to Pugin’s and Salvin’s ideals. Hohenschwangau, like certain castles built in this period on the Rhine, exploits the Picturesque possibilities of a fine site and the nostalgic overtones of a district with a romantic medieval past. Schloss Berg in Bavaria, which owes its present very domesticated Gothic character to the work done there by Eduard Riedel (1813-85) in 1849-51, hardly deserves mention in this connexion any more than do Schinkel’s more or less medievalizing country houses, so crisp and regular is their design. Curiously enough, the vast Schloss at Schwerin, begun by G. A. Demmler (1804-86) in 1844, is a more elaborate and extensive example of _François I_ than anything this period produced in France (Plate 57B). It is also notably Picturesque, with innumerable towers and gables disposed around the sides of an irregularly polygonal court. Stüler carried this extraordinary pile to completion after Demmler left Schwerin in 1851. Not very Picturesque, but representing another sort of medievalism, were two Venetian Gothic houses Am Elbberg in Dresden, built with considerable archaeological plausibility by an architect named Ehrhardt in the mid forties. They provide a curious premonition of Ruskin and the High Victorian Gothic of England (see Chapter 10). Semper’s Gothic Cholera Fountain of 1843 in Dresden has already been mentioned. As in France, much energy went at this time into the restoration and completion of major medieval churches in Germany. Most notable in this connexion was the work on Cologne Cathedral begun in 1824 by F. A. Ahlert (1788-1833), continued by E. F. Zwirner (1802-61), and finally completed by Richard Voigtel (1829-1902) in 1880. Assisting Zwirner, who had worked earlier under Schinkel on the Kolberg Town Hall, was (among others) Friedrich von Schmidt (1825-91), after 1860 the most important Gothic Revivalist in Austria (see Chapters 8 and 11). No more than in France did this activity in ‘productive archaeology’ in Germany lead to new building of much interest, not at least until Schmidt began to work in Vienna.
