Неглинная
Northeastern side of Tverskoy District (east of Petrovka Street) lagged behind Tverskaya Street and Moscow's east side due to frequent floods on the Neglinnaya River. First attempt to control the river, proposed in 1775 by Matvey Kazakov, materialized in 1792 Neglinnaya Canal, which was running parallel to the river. Once the canal was completed, the old river bed was filled with earth. In 1817–1819, the channel was covered with masonry vaults, locking the stream in a tunnel. This created Neglinnaya Street, the youngest street inside Boulevard Ring, but did not rule out future floods. The most recent flood, in 1973, led to complete rebuilding of the aging tunnel (1974–1989, see 1965 flood photos) Another legacy of the Neglinnaya river survives in Central Baths (1890) and Sandunovsky Baths (1896).
