On 1st September 1939, at 4.45 am, Hitler’s Germany launched an attack on Poland with no prior warning, and the following day the Swiss government ordered the full mobilization of the armed forces, under the command of General Guisan. Bells rang for many hours in quick successive strokes. The fear that the conflict would also involve Switzerland spread everywhere. Nine months later, during High Mass, the people of Bissone (known as Bissonesi), urged by a priest named Felice Camponovo, made a vow to St. Nicholas of Flüe, the patron saint of the Swiss Confederation, to build a chapel in his honour if the war were to continue to spare our country. The date was 19th May 1940. Once the conflict was over with no consequences for Switzerland, the chapel was erected on a design by the architect Antonio Bordoli and thanks to the work of Ugo Orsatti, a master builder, then mayor of Bissone. Construction was completed in May 1949. Since then the chapel has been a place of reflection and holds a special place in the hearts of the residents of Bissone.
