In this beautiful night-time capture by Jacopo Martocchi, we see fog illuminated by the city lights of Chiavenna, Italy. The artificial light gives the fog a ‘lava-like’ quality.

Chiavenna is a city (municipality) in the Province of Sondrio in the Italian region of Lombardy. It is located about 100 kilometres (62 mi) north of Milan and about 40 kilometres (25 mi) northwest of Sondrio. As of 31 December 2004, it had a population of 7,263 and an area of 11.1 kilometres (6.9 mi). The surrounding alpine region is known as Valchiavenna, located to the north of Lake Como.

Valchiavenna is traversed by the rivers Mera and Liro and can be divided into three parts which branch from the confluence of these rivers.
