"More than 20,000 football fans from different countries took free tours around the capital's center. The excursions were organized by Moscow's Sports and Tourism Department as part of the 'Moscow is the capital of world football' campaign. The walking and bus tours were available during the 2018 World Cup, from June 14 to July 15," the mayor's office said in a statement.

The tours, which took the fans to Moscow's historical and modern sporting facilities, were organized in eight languages, with tourists from across Russia, Germany, the United Kingdom, Mexico and China making up the majority of the visitors.

"Thanks to the tournament, the whole world saw that Moscow was a friendly modern city with a rich culture and history," head of Moscow’s Department of Sports and Tourism Nikolay Gulyayev said as quoted by the mayor's office.

Russia's first-ever FIFA World Cup kicked off on June 14 and came to a close on Sunday after 64 games were played at 12 venues in 11 cities.
