Moscow-850 (Russian: Колесо имени 850-летия Москвы) was a Ferris wheel in the amusement park "Moscow-850" on the territory of VDNKh (Exhibition of Achievements of National Economy), built for the 850th anniversary of Moscow.
According to Gnezdilov, in 1994 he received an offer to develop the abandoned area of the territory of VDNKh and presented a project of an amusement park with attractions, the opening of which was symbolically timed to the forthcoming celebration of the 850th anniversary of Moscow.
The project was discussed at the level of the city government and the Mayor Yuri Luzhkov suggested that the Ferris wheel would be the highest in Europe.
[2][3] In 2010, a conflict arose between the tenant of the site (the "Russian Exhibition of Attractions", a subsidiary of the group "Mir") and the management of VDNKh.
This incident gave VDNKh (the name of the All-Russian Exhibition Center, VVTs, from 2014) an occasion to publicly announce the danger of using attractions.
