The European Championship is commonly known as the UEFA Euro or simply Euro, which is a major international football tournament held every four years. As for the specific location of the tournament, it varies each edition.
The hosting rights of the UEFA Euro are awarded to a single or joint host country/countries by the Union of European Football Associations (UEFA). In some cases, multiple countries can cohost the tournament to spread the matches across different venues and cities.
For example, the latest edition of the UEFA Euro, held in 2021, was originally scheduled to be hosted by a single country, which was supposed to be 12 different cities in 12 different European countries. However, due to the COVID19 pandemic, the tournament format had to be modified, and it was eventually held in 11 cities in 11 countries.
To find out the specific locations of any past or future UEFA Euro tournaments, it's recommended to refer to official UEFA announcements, football news websites, or the official UEFA Euro website for the most uptodate information. It's worth noting that the official language for most UEFA communications is English, so it can be helpful to search for the information using English keywords or visit the English version of UEFA's website.
