Mara sez, "The Swiss Alpine engineers: Were they drinking or suffering thru a very bad winter of cabin fever when they dreamed up that idea for bringing tourists to the top of the Jungfrau mountain (4,158 metres, or 13,642 ft)? A thousand-meter-high lift built inside a gigantic Eiffel Tower structure, put in the middle of an Alpine valley, with the top of the tower connected to the top of the Jungfrau by a suspended cable car? It's an amazing undated drawing, probably from the end of the 1800s."
(Thanks, Mara!)
