About 120 km (74.5 miles) northeast of Turin, Italy, lies a hamlet called Viganella. It’s a remote commune of a couple hundred German Buddhists situated at the bottom of a steep-sided Alpine valley, right up against the Swiss border. Every year from November 11th to February 2nd, the sun disappears for Viganella. To combat this, the mayor came up with a novel solution. Build a gigantic mirror on a nearby peak to reflect sunlight on Viganella’s main square below.
