Iberian cathedrals are some of the most impressive religious buildings in Europe. Mostly erected between the twelfth and fifteenth centuries, they are also the outcome of regional phases of growth and development. This article discusses this period favourable to the building of religious structures in the Iberian Peninsula, considering local dynamism, the religiosity of adherents and stimuli from the economic development of the surrounding areas. Using models of spatial autocorrelation, we observed different results for the Portuguese dioceses and for the Spanish ones. Spanish dioceses, in particular, exerted competitive effects on surrounding dioceses, making the erection of new cathedrals close to a diocese with an old or a valued cathedral less probable. It was also observed that the dynamism of cathedral construction in a given diocese tended to be replicated in the closest dioceses between the twelfth and fifteenth centuries.

伊比利亚大教堂是欧洲最令人印象深刻的宗教建筑之一。它们大多建于十二至十五世纪之间，也是区域增长和发展阶段的结果。本文讨论了这一有利于伊比利亚半岛宗教建筑建设的时期，考虑到当地的活力、信徒的宗教信仰以及周边地区经济发展的刺激。使用空间自相关模型，我们观察到葡萄牙教区和西班牙教区的不同结果。尤其是西班牙教区，对周围教区产生了竞争影响，使得在拥有旧大教堂或有价值的大教堂的教区附近建立新大教堂的可能性较小。人们还观察到，十二世纪至十五世纪期间，某个教区的大教堂建设活力往往会在最近的教区中复制。
