Fire of Moscow
Upper-class population grew stronger after the Fire of Moscow (1812), when the main streets were rebuilt in Neoclassical architecture by disciples of Matvey Kazakov. Grand 2–3 mansions were more common in Prechistenka, smaller single-story buildings—in Ostozhenka Street; some of them survive to date. However, the territory between facades of Ostozhenka and the embankment were a maze of wooden huts, small factories etc.; this disparity continued until the 1990s, and even today there are many run-down, condemned wooden houses.
