Spain is a non-denominational country in which Catholicism is the main religion, although there are also important representations of communities such as Muslims, Jews and Protestants.
Catholic tradition played an essential role in the founding and layout of the city, which has been a pilgrimage destination since the 9 th century due to the Apostle James' tomb. In fact, Santiago is one of Christendom's holy cities, along with Rome and Jerusalem . Compostela has also been a see since the 12 th century.
