attendance increased to nearly 17,000. By then Orlyonok had grown to an area of 3 square kilometers, with 60 buildings, including the dormitories, the "Young Pioneer Palace" (with a winter swimming pool filled with sea water, and a cinema), secondary school, medical building, Museum of Aircraft and Cosmonautics, astronomical observatory, sports stadium, playgrounds and a winter sports hall. There were more than 200 hobby groups of 50 different kinds, mostly in polytechnics, sports, and aesthetics. Orlyonok had its own passenger ship, 45 yachts, and many motor boats and rowboats. In the early 1990s, when the Young Pioneer organization of the Soviet Union was dismantled, the camp attendance in Orlyonok was greatly decreased; however, attendance has increased since 2000, as the camp was nostalgically associated with the Young Pioneer camps of the past. It is believed that between the years 1960 and 2010 Orlyonok hosted over 800,000 children. On July 12, 2010, Orlyonok celebrated their 50th anniversary. It welcomed guests from all over Russia and abroad, all ages and walks of life, whose life was connected with Orlyonok. The celebration culminated with a special concert and fireworks at the central stadium. In 2011 Orlyonok hosted a delegation from UNESCO reviewing Orlyonok admission to the UNESCO Associated Schools Project Network. In 2012 Orlyonok was admitted to the UNESCO ASPNet. On February 5, 2014, Orlyonok hosted the final part of the 2014 Winter Olympics torch relay. A relay torch was lit with the Olympic flame next to the Memorial Stone, from where it was carried throughout Orlyonok by 15 torchbearers covering a distance of approximately 3 kilometers.
