What were renaissance architects forced to focus their attention on building in rome?

Renaissance architects in Rome were primarily focused on rebuilding and enhancing religious structures, particularly after the devastation of the city during the late medieval period. They aimed to create grand basilicas and cathedrals that reflected the ideals of beauty, harmony, and proportion, often incorporating classical elements from ancient Roman architecture. Key projects included the redesign of St. Peter's Basilica and the construction of various churches and palaces that showcased the era's artistic and architectural innovations. This focus was also driven by the Catholic Church's desire to demonstrate its power and influence during the Counter-Reformation.
