About the federal territory «Sirius»
The Sirius federal territory is located in the Imeretinskaya Lowland between the Mzymta and Psou rivers and surrounded by the Caucasus Mountains and a unique nature reserve (Caucasian Biosphere Reserve and Sochi National Park). The territory hosted the 2014 Winter Olympics, following which Russian President Vladimir Putin initiated the foundation of the Sirius Educational Center for talented children from all across the country.
Now, based on the Olympic legacy, Sirius also accommodates and develops the University of Science and Technology, the Presidential Lyceum, modern laboratories, as well as cultural and sports infrastructure. Both children and their teachers and mentors study here. Scientists create innovative solutions thanks to the vast capabilities of the Sirius Science and Technology Center. Engineers work on delivering and adapting such solutions to urban spaces. National standards in education, science, culture, sport, and other fields are set here to later be scaled all over the country. The open Sirius federal project aims at identifying and developing talents of all ages for the benefit of the whole country and each and every Russian citizen as well.
