The Spanish architecture refers to architecture carried out during any era in what is now modern-day Spain, and by Spanish architects worldwide. The term includes buildings within the current geographical limits of Spain before this name was given to those territories (whether they were called Hispania, Al-Andalus, or were formed of several Christian kingdoms). Due to its historical and geographical diversity, Spanish architecture has drawn from a host of influences.The arrival of Modernism in the academic arena produced figures such as Gaudí and much of the architecture of the 20th century. The International style was led by groups like GATEPAC. Spain is currently experiencing a revolution in contemporary architecture and Spanish architects like Rafael Moneo, Santiago Calatrava, Ricardo Bofill as well as many others have gained worldwide renown.
