The monument to Yaroslav the Wise was designed by sculptor Ivan Kavaleridze in 1958. Subsequently, his project was significantly enlarged and in 1997 the city administration placed it at the Golden Gate. It calls "a man with a cake" among people – this is how a model of a building on a "plate" looks like. In fact, the bronze prince holds in his hands the a model of the most expensive building that was guarded by the Golden Gate - the temple of St. Sophia.
By the way, if you look behind Yaroslav's back, you can see his secret. Three palms are printed in bronze. By the time of creating the monument, Kavaleridze was not alive, and the new masters wanted to show that they have taken a hand to the monument. In a literal sense.
