Architecture Quest: Decoding Watchtower Design

Study the tower and surrounding terrain. In this exercise, separate what you can see (such as an opening or a tower) from what you infer about its purpose.

Sketch a tower from a photograph on the location page. Label two visible features. Add one question about how the design worked, clearly marked as a question rather than a proven fact.
