Barcelona have been champions of Europe five times but it took them until 1992 to lift the trophy, then known as the European Cup, for the first time.
Here, the PA news agency marks the day they beat Sampdoria at Wembley for their first win in the competition.
Barcelona's first final, against Benfica in Bern in 1961, started well enough when Sandor Kocsis gave them a 21st-minute lead.
But Benfica hit back to score three times through Jose Aguas, Antoni Ramallets and Mario Coluna and while Zoltan Czibor made it 3-2 Benfica lifted the trophy.
It was the first final not to include Real Madrid, who had won the previous five.
Second time unlucky
It took until 1986 for Barca to return to the European Cup final – where they faced Steaua Bucharest in Seville.
The team, including former Tottenham and Scotland striker Steve Archibald, were held to a 0-0 draw after extra time.
Jose Alexanko, Angel Pedraza, Pichi Alonso and Marcos all had their penalties saved by Helmuth Duckadam as Barcelona lost the shoot-out 2-0.
Barca's dream of reaching the top of European club football was finally realised when they toppled Sampdoria 1-0 in London in May 1992.
The team, managed by Johan Cruyff, included Pep Guardiola, Hristo Stoichkov, Michael Laudrup and Andoni Zubizarreta and also won LaLiga that season.
