Culture is a complex set of customs and values of a group of people that are transmitted through learning. While in the beginning culture had only material characteristics, today it has taken on the characteristics of a spiritual process as well. Culture is generally understood as a set of values, customs and beliefs according to which a certain group of people live and it is something created by man and not nature. Cultures are expanding in space, and in modern times this expansion has become an increasingly rapid and complex process, which is why new understandings of the concept of culture have developed. Italy and the Republic of Croatia are neighboring countries that, perhaps precisely because of their proximity, have adopted many common customs, beliefs and content, and not only from a cultural point of view. The influences of mixing different cultures, including the Italian one in the Croatian area, are visible in Croatian architecture, music and art. There are more and more Italian citizens in the Republic of Croatia and Croatian citizens in Italy, which mixes their customs, traditions and beliefs.
