On most evenings, the Baltic sky over Tallinn rests quietly — a soft gradient of navy blue fading into the horizon. But sometimes, if the conditions are just right, something extraordinary happens.

Something we usually think belongs to Lapland, Iceland, or faraway Arctic wilderness.

Yet there I was, standing above Tallinn’s rooftops, watching a green and violet curtain of light shimmer across the night sky.

Even after guiding more than a hundred tours through Tallinn’s UNESCO-listed Old Town, the feeling never gets old. There is something timeless and quietly magical about these cobblestone streets — a mix of medieval drama, northern calmness, and hidden corners that reveal themselves differently with every walk.
