The clockwork was bought in England and put by the Bulgarian revolutionary Oton Ivanov. It is a real piece of art. The clockwork is closed in a wooden “box” to which lead winding narrow staircases. The face of the clock is situated at the front. It controls clock movement and punctuality. By system of shafts and cogwheels the hands of the clock move outside the tower. The clockwork is set in motion by weights hanging in the middle of the tower. When the clock needs repair its hands are moved manually. In such a way the people of Varna can always be punctual on their dates.
