This course will examine the transition of Western Europe into a fortified landscape from the mid-11th century until the advent of large-scale artillery in the mid-15th century. In addition to tracking technological and stylistic changes over time, this course will identify the discrete elements of fortification that were combined into a variety of castle plans. Natural resources and physical topography will emerge as central factors in the choice of site and design for medieval castles. As a way of investigating these topics, students will digitally reconstruct a historical or imagined castle in 3D graphics at a specific place and time covered in the course.
