4 April 1866 in Kiev was an assassination attempt upon the life of Tsar Alexander II. The attempt was unsuccessful and in honour of Tsar rescue, was organized competition of the gates projects.
The project from Viktor Hartmann (Russian architect and founder of the “Russian Style” in architecture) was done in a old Russian style. The gates were giving an impression of Kiev as a old Russian capital. But later on the competition was cancelled and successful project was not realized (The Gates were never built!!!).
