former city council

Building of management of the Sberbank in Saint-Petersburg, the former building of a thought at the corner Nevsky prospect and the Duma street. Passing by, pay attention to six-coal end of a turret, at once under a lightning rod. It is the second broadcasting station of optical telegraph. The first settles down on Winter Palace, from West side, and has the same six-sided form. The signal of optical telegraph, in good weather, from Petersburg to Warsaw passed for 15 minutes (1200 versts, 150 station of optical telegraph). The optical telegraph has existed absolutely not for long and has been forced out by the appeared electric telegraph, and subsequently — wireless (as at a birth named radio).
