Gilly would have been overshadowed by his son Friedrich (1771-1800) had the latter lived, or so one must judge, not from his modest Mölter house in the Tiergartenstrasse in Berlin of 1799, but from certain major projects. One, of 1797, is for a monument to Frederick the Great which was widely and deeply influential for many years to come; another, of 1800, is for a Prussian National Theatre, improving upon Ledoux’s at Besançon as regards the interior and very original in its external massing. The monument raised a Greek Doric temple on a tremendous substructure of the most abstract geometrical character, surrounded it with obelisks, and set the whole in a vast open space, unconfined but—as it were—defined by subsidiary structures of very fresh and varied design (Plate 9A). The handsome gateway to the square seems to provide evidence of Gilly’s familiarity with such a highly personal work of Soane as his entrance arch at Tyringham (Plate 6A); however, the general tone of somewhat funereal grandeur recalls rather the monumental projects of Ledoux, Boullée, and the younger men of France who designed so much and built so little in this decade. Other contemporary Berlin architects, such as Heinrich Gentz (1766-1801), who built the old Mint in 1798-1800, and Friedrich Becherer (1746-1823), who built the Exchange in 1801, while up-to-date stylistically, were much less accomplished than Friedrich Gilly. His artistic heir was his fellow pupil Schinkel, whose architectural career really began in 1816 (see Chapter 2). [Illustration: Figure 1. Friedrich Weinbrenner: Karlsruhe, Marktplatz, 1804-24, plan ]
