"Lost" medieval church of Dunwich found with modern technology

Marine archaeologists believe they have discovered a medieval church which tumbled off an eroded cliff into the ocean in Suffolk County, England. The remains were discovered using sonar and underwater cameras.

Dunwich, England was once a thriving community until 500 years ago when part of the town, including St. John's Church, was washed into the North Sea by erosion. Now, after many years of research, experts believe that they have found the church under layers of silt.
