More Songs About Chocolate and Girls

A walk along the Toblerones this morning.
Song by The Undertones
And here's some explication about the route: 

"Toblerones" was the popular name for the tank traps set up as defensive lines between Bassins and Nyon in the second world war. Their triangular shape recalls the "peaks" of a Toblerone chocolate bar, and that explains the name given to the 3,000 or so concrete triangles – each as tall as a man. The "Toblerones" are arrayed along a stretch of about ten kilometers between the Jura foothills and Lake Geneva. An educational trail focusing on history follows the traps.

Around 1940, when German troops were attacking neutral countries such as Belgium and Norway, fears also reached very high levels in Switzerland. This prompted the start of construction work on the "Promenthouse Defence Line": chunks of concrete were set up one after another along the courses of rivers and streams.
