Leicester players and officials embraced on the field after a 1-0 victory over Chelsea gave them their first FA Cup title but there was a broader celebration at Wembley.
The final of the oldest competition in the world, played at the national stadium, was the perfect occasion for the game to significantly open its doors again to supporters.
The game was, technically, part of the UK government's Events Research Programme, designed to measure the impact of the return of mass events.
All fans had to have proof of a negative COVID-19 test in order to gain access to the stadium.
Fans will be back in Premier League grounds, in relatively small numbers, for the final two rounds of games but the hope is that Wembley will see even bigger numbers for the semi-finals and final of Euro 2020 in July.
