Moscow's first free public hospital. The project, supported by the dowager Empress Maria Feodorovna, was completed in 1796–1802 by Matvey Kazakov. Although the Golitsyn family owned lands nearby, the hospital was set on Stroganov family land. Hospital construction continued on Kaluga Road throughout the next century. Today, these hospitals belong to Yakimanka District and are known as First City (Первая Градская). 19th century The Fire of 1812 swept the entire area except for a few blocks in the southern end of Bolshaya Yakimanka and Kazakov's hospital (which took care of both Russian and French troops). The construction of the Babiegorodskaya Dam and the clearing of the Vodootvodny Canal in the 1830s reduced the flood hazard, but the land remained cheap. This led to the steady industrialization of Zamoskvorechye. For example, Gustav List set up his first metalworking factory in Boloto, directly across from the Kremlin (his mansion, also in Boloto, would later house the British embassy). While most of Yakimanka remained a traditional, low-rise merchant neighborhood, a cluster of large five- to seven-story factory buildings emerged in Golutvin and Bersenevka (Golutvin was the birthplace of Pavel Ryabushinsky). Most of these are now converted to office space, while Krasny Oktyabr chocolate factory (originally Einem) is scheduled for conversion soon. Hotels catering to businesspeople were built nearby in Boloto and Balchug Street. In 1896, the city built an electrical power plant in Zamoskvorechye District (MOGES-1, the oldest existing power plant). The second power plant, built specifically for the tram network, emerged in Yakimanka District, also in Bersenevka, and operates today. Since that time, electrical and oiling offices are major tenants on the Balchug island. The late nineteenth century was also a time of charity and social experiments. The Tretyakov Gallery, which started as Pavel Tretyakov's private collection in the 1850s, opened to the public in 1892. The existing building, with a facade designed by Apollinary Vasnetsov, was completed in 1899–1904. Pavel Tretyakov also financed the construction and operation of the free housing for widows and children of Russian artists, located north from the Gallery. Morozov Hospital, the city's first surgical hospital for children, started in 1896 as a two-room Red Cross clinic. The Morozov family financed construction of the two-story existing building in Bolshaya Polyanka. Another free hospital was operated by the Marfo-Mariinsky Convent. Finally, the city and private philanthropists also provided cheap or free housing; the largest public housing projects were
