The main Idea of this research paper is to make a comparison between the st Pete’s Basilica with the Church of the Sagrada Familia. But the must important thing is that the St Pete’s Basilica I chose it as the principal building and the church of the Sagrada Familia is the secondary, also is very important that the part of the St. Petes Basilica that I selected is just the Renaissance part of the building the part that was made by Michelangelo. (Do not use the part the was made in Baroque architecture style, you can only write a little bit about that style.) Focus on the Renaissance architecture of the building. About the sources you can use google, google scholars, any book, etc. that’s fine. Thanks for the help and have a good weekend.
