This course will explore domed structures through history, from the ancient world to the present. Each of the lectures will present two or more domes, looking into not only their structure and construction, but also who built them and why. The zoom lectures will be richly illustrated with photos and diagrams. Comparisons of the 10+ structures will be made regarding size (plan and volume) and construction methodology. All the domed structures in the course are extant (except one) so lectures will include current photography and current uses.
