The twinning with the two German municipalities of Dürnau and Gammelshausen was the first to take place. We have been twinned since 1988, the year in which, taking advantage of the sporting relations that existed between the athletic entity UR Laru and the sporting club GSB Dürnau, and with the occasion of the centenary of the Dürnau sporting club, the mayors of Dürnau and Gammelshausen approached the mayor of Mataró to invite him to attend the celebratory acts of their centenary, while at the same time initiating and signing the twinning of the two municipalities with Mataró.
