Lost Villages of medieval England
Only had time for a peek, due to slow loading, but will try later. Aerial photos taken in the 1930s and 1940s set the world of medieval history reeling with delight, as the remains of abandoned medieval villages (yes, and some Roman remains) were visible in low-angled light. The depopulation of England in the series of plagues after 1348 meant many villages were utterly lost, sometimes even the names gone from local memory. By using the photographs, archaeologists could find and excavate sites undisturbed for centuries, and huge amounts of important information was recovered. Being an ex-mediaevalist, I have a soft spot for these photos.
