Mariinsky Concert Hall can be accessed from the "cultural" lobby, located on one level below, where the Mariinsky Theater's branded outdoor amphitheater/staircase is located, oriented towards a modern media wall for showing video materials that envelops its staircase from three sides. This staircase goes up to the square level, where visitors enter the lobby of the Mariinsky Theater
Escalator takes up visitors from the square level to the atrium volume of the large, elegant Mariinsky Foyer, which is located next to the rooftop terrace above the museum. From this extraordinary space, which also serves as a place to stay during the intermission, visitors can enter the modern 950-seat Mariinsky Concert Hall and the 350-seat Chamber Theater.
