A supernatural beauty? No, this is a kind of magic, and it depends on a number of stage effects or tricks. First, there is the architecture ‒ buildings which are sketched on the air rather than built of solid materials, brick upon brick. Then there is water ‒ water which runs like a liquid mirror through the city's midst, throwing down a second sky to match the one above and leaving the city's buildings floating in between. In winter there is the snow ‒ another veil that blots out the dirt and the ground. But, above all, there is the light ‒ the low northern light, a perpetual evening luminosity which casts a soft sepia tint over the lines of buildings.
