Sochi Olympic Park Sochi Olympic Park is an Olympic Park that was constructed for the 2014 Winter Olympics and 2014 Winter Paralympics. Located in the Adler City District of Sochi, Imeretinsky Valley, on the Black Sea (about 4 km, or 2.5 miles) from Russia's border with Abkhazia/Georgia), the Olympic Park houses the main Olympic Stadium used for the Games' ceremonies, and the venues that were used for indoor sports such as hockey, figure skating, curling, and speed skating. It also houses training facilities, the Olympic Village, the international broadcasting centre, and other amenities. The park was designed so that all of the venues would be accessible within walking distance of each other. The venues are situated around a water basin containing a fountain known as "The Waters of the Olympic Park"; designed by California-based WET (which also designed the cauldron for the 2002 Winter Olympics in Salt Lake City), the fountain measures 5.3 meters in diameter with a capacity of about 700,000 gallons of water, featuring more than 250 nozzles and jet systems that can create fog and choreographed water displays set to music.
