This shot is from inside a lighthouse on the coast of the South of France (Cap Camarat) - now closed to the public unfortunately :-(
I haven't managed to find any information on the web concerning this lighthouse. The juiciest piece seems to concern the existence of a French mine-laying submarine (66m long) named the Rubis (designed in 1925 and launched in '31) which was used duing World War 2 to lay nearly 700 mines that sank or damaged at least 25 ships. She survived to the war, was stricked during 1949 and scuttled in January 1958 off Cap Camarat, between Cavalaire and Saint-Tropez. The wreck is popular among French and Italian scuba divers: the hull is in good condition, and lies in navigation trim on a sandy bottom at a depth of -40m; the water is always very clear.
