The Dolomiti: Where the Mountains Turn Pink at Sunset

There is a moment at sunset in the Dolomites that no photograph truly captures. The sun drops behind the western peaks, and for perhaps fifteen minutes the vertical rock towers to the east begin to glow from within — starting with a warm pink, deepening to amber, then fading through violet into grey. This is the Enrosadira, the 'turning rose' in the Ladin language, and it happens because dolomite rock — the calcium magnesium carbonate that gives these mountains their name — reflects the dying light differently from ordinary limestone. It is a geological accident of extraordinary beauty, and the people of these valleys have been trying to explain it with myths for as long as anyone can remember.

The Dolomites stretch across northeastern Italy, spanning the provinces of Bolzano, Trento, Belluno, Pordenone, and Udine. They were formed when an ancient tropical sea — the Tethys Ocean, which covered this part of the world 230 million years ago — left its coral reef deposits on what would eventually become the Alps. The distinctive towers, needles, and sheer cliff faces that make the Dolomites unlike any other mountain range are the eroded remains of those ancient reefs. In 2009, the Dolomites were declared a UNESCO World Heritage Site for their 'outstanding universal beauty' — a rare designation usually given to cultural sites rather than natural landscapes.

The man who identified and described the distinctive rock is himself part of the mountains' history. Déodat de Dolomieu was a French geologist who, in 1791, published a paper describing the unusual calcium magnesium carbonate rock he had collected in these mountains. The rock — and eventually the mountains — were named after him. Dolomieu had a remarkable life: he survived a cave-in in a Maltese prison during the Napoleonic wars, was ransomed back to France, and died in 1801 at the age of 50, having given his name to an entire mountain range and a mineral. The rock dolomite is found in limited quantities around the world, but nowhere else does it form vertical towers and needles of this scale.

What sets the Dolomites apart from other Alpine areas is not just the geology but the culture. The valleys are home to three linguistic communities: Italian, German-speaking Südtiroler (descendants of the Austrian Tyrol, whose territory became Italian after World War One), and the Ladin people, who speak a Rhaeto-Romance language descended from Latin and have preserved their distinct culture for over 2,000 years. In the Ladin valleys — Val Gardena, Val Badia, Livinallongo — road signs appear in three languages: Italian, German, and Ladin. Menus, newspapers, and television programmes exist in Ladin. The culture is genuinely trilingual in daily life, not just on ceremonial occasions.

Ladin mythology is full of mountain spirits, enchanted kings, and the explanation for the Enrosadira: that a king trapped inside the rocks is trying to weave a garment of moonbeams, and the pink glow is the light leaking through the cracks. The Tre Cime di Lavaredo, the Marmolada glacier, the Seceda ridgeline, the Alpe di Siusi — each one has its own story, its own season, its own impossible landscape. The Dolomites were also the site of some of the most brutal mountain warfare in history during World War One, when Austrian and Italian troops fought at altitudes above 3,000 metres, tunnelling into the rock to plant explosives beneath each other's positions. The remains of that war — trenches, tunnels, cemeteries, and the Marmolada's slowly melting ice, which has been releasing soldiers' bodies frozen since 1917 — are a presence throughout the region.
