DOVER, England – The Church of St. Mary-in-Castro is one of many sites to see at Dover Castle. Participants in an RAF Lakenheath Information Tickets and Travel trip went to the castle on March 26, 2011. On the right side of church is a Roman pharos, or lighthouse, which was probably built in the first century A.D. (U.S. Air Force photo/Staff Sgt. Stephen Linch)
