We apologise to the England fans among you: we're about to ask you to try and dig up old memories of semi-finals.
Over the past 60 years, the Euros has been hosted across the continent - but we want you to tell us where. Of course, that was the idea for 2020 - but... yeah, you remember what happened.
We're looking for the host cities of every match between the last four of the European Championships – you just need to name any city that held a game.
Feel sorry for the spectators who went to the 1968 semi-final between Italy and the USSR. The match ended 0-0, went to extra time (where no one scored), and was finally settled with a coin toss.
