This comparative study examines the architectural design, historical context, and artistic significance of the churches of San Giorgio Maggiore and Santissimo Redentore, both masterpieces by Andrea Palladio in Venice. The research investigates Palladio's innovative use of classical elements, spatial organization, and interplay of light and shadow in these religious structures. Through detailed analysis of the churches' facades, interiors, and surrounding environments, this study provides insights into Palladio's architectural genius and its impact on the Venetian cityscape throughout his time. The aim is to understand how these churches reflect Palladio's architectural ideas, as well as the historical and cultural conditions of 16th-century Venice.
