It constitutes the newest field since it did not exist when the first UNESCO clubs were founded, in Japan, in 1947. The association UNESCO for Interreligious Dialogue together with UNESCOCAT are doing an enormous task with the City Councils from many Catalan cities who are interested. They produce a map that contains the religions of each municipality, they disseminate the interreligious calendar, the interreligious dictionary and the didactic material.
The associations of Lleida and St. Adrià are working in this field as well.
Prayers, congresses, workshops, courses, conferences, round tables, etc. are organised in order to know better the different religions.
