This course looks at Baroque Architecture in many of its forms: as a showcase for Counter-Reformation churches in Rome and at the Vatican, as it was received in Northern Europe in France and England, and how the Spanish Baroque made the journey across the Atlantic and determined the built forms of colonial power for much of the Americas. The second part of the course takes an in-depth look at the development of curved surfaces in architecture and the influential contribution of two Roman architects, Gianlorenzo Bernini and Francesco Borromini, which revolutionized the very concept of what buildings could look like well through the modern era.
