Moscow’s Circle of Light festival brought together 3 million people this year, taking place at nine venues across the Russian capital, with the Polytechnic Museum and Ostankino Park hosting the festivities for the first time. The multimedia musical "Seven Notes" at Moscow's Grebnoy Canal opened the light show. The event has been held in Russia’s capital city since 2011. At the very first festival, more than 360 installations were put on display, back then Red Square and Manezhnaya Square, along with Gorky Park were the main venues for the event.
