The middle section of the Boulevard is occupied by the semi-circular square with the monument to A. E. Richelieu in the center. The buildings of the former stock exchange and the Vorontsov Palace terminate the Boulevard on each end to form an integral balanced whole. The architectural rhythm of Primorsky Boulevard, enhanced by horizontal terraces, is interrupted by the vertical line of the grandiose Potemkin stairs terraces. Primorskiy Boulevard Pictures
