A 30-strong delegation from Clichy, Southwark's twin town near Paris in France, visited the borough this weekend.
Mayor of Southwark Cllr Althea Smith gave the visitors a tour of some of the borough's attractions including Tate Modern, Shakespeare's Globe and Borough Market before heading to a reception at the home of local businessman Prem Goyal OBE.
At the reception people from Clichy and Southwark mingled and got to know more about each other's areas.
Deputy Mayor of Clichy Serge Setterahmane said visiting Southwark was "always great".
"We have had a twinning [agreement] since 2005," he said. "It's getting older and better. And it's very important for us to have the people from Clichy come here and visit our twin in this city... It's good for the friendship, for the exchange of people between the schools. For that it's very important to have this kind of twinning."
Mayor of Southwark Cllr Althea Smith said: "I'd like to thank Prem for entertaining the Clichy delegation. It was a lovely gesture and I know that he's very supportive of our community.
"All the delegates enjoyed themselves and it was a beautiful reception. It's important to empower the link, and not just use it as a friendship, but to also use it to promote business between Clichy and Southwark."
