Corsham has had a twinning relationship with the town of Jargeau, France since 1981, and has an active twinning association. Corsham holds an annual twinning event in which musical and charity events occur, accompanied by French food and wines. There is also a boules competition for the Peter Henderson trophy which is named in memory of a local doctor and former chairman of the twinning association. As part of the 2008 event, a mock Storming of the Bastille was staged to celebrate Bastille Day, Corsham Town Hall standing in for the Parisian prison.
