My home city of Norwich is twinned with Rouen in France, Koblenz in Germany, Novi Sad in Serbia & El Veijo in Nicaragua. The three European cities are pretty historic like Norwich - El Viejo was chosen as a twin to help after the political upheaval in that country. Rouen Road & Koblenz Avenue are named for the twin cities and we have the Novi Sad Friendship bridge as well. My old secondary school was twinned with a school in Rouen, so in 1981 I had a fortnight there and stayed with a French family which was fun. As I remember we had a civic reception with the Mayor of Rouen & did some rail trips from Rouen to Paris, Dieppe and Cleres on SNCF.
