On the pedestal you can see not only the Princess but also St. Andrew, the First-Called Apostle (who predicted that on these hills will be a great city), and Cyril and Methodius (they became missionaries of Christianity among the Slavic peoples. They received the title "Apostles to the Slavs"). Olga was the first ruler woman who took Christian tradition, she was baptized in Constantinople.
The monument was opened in 1911, the sculptor was Ivan Kavaleridze, but eight years after the Olga’s statue was throw down and it was buried right there on the square. The monument itself should have been a part of a big project called “The Historical Path”. It should have been an alley of statues illustrating the centuries-old history of Kiev. Olga returned to her pedestal only in 1996, but not the original one, only her copy made of white Carrara marble. Original Olga you can find on St. Andrew’s descent.
