they also did one on top of Mont Blanc (highest mountain of Europe): http://jaccuzzi.ch/html/affichjacc.php?id=112 and inside a cave where you need to dive to reach the spot:

"It is home to the Caucasus Mountains, which contain Europe's highest mountain, Mount Elbrus"
http://en.wikipedia.org/wiki/Caucasus
NB I've always thought of Europe stopping at the Urals, the Caucasus and the Bosphorus.
(From Wikipedia):
The generally accepted highest summit is Mount Elbrus (5,642 m or 18,510 ft) in the Caucasus, appearing on both the Bass and Messner lists. However, because the location of the boundary between Asia and Europe is not universally agreed upon, its inclusion in Europe is disputed: if the Kuma–Manych Depression is used as geological border between Asia and Europe, Caucasus and Elbrus lie wholly in Asia. If the Greater Caucasus watershed is used instead, Elbrus' peaks are wholly in Europe, albeit close to the border with Asia. Mont Blanc (4,810 m or 15,781 ft), lying on the border between France and Italy in the Graian Alps, is seen by some to be the highest mountain in Europe.
