Tonight you walk through hotels that were built for guests who never arrived — and the concrete, tile, and silence they left behind. You begin on the Baltic coast of Germany, where a single building stretches four and a half kilometres along the beach — Prora, designed by Clemens Klotz for the Nazi Kraft durch Freude program between 1936 and 1939, planned for twenty thousand simultaneous holidaymakers in identical rooms measuring two and a half by five metres, with a four-hundred-thousand-square-metre gathering ground and an underground railway connecting eight blocks, none of it completed, the plumbing never connected, the rooms occupied only by bombing refugees and later by soldiers. You cross to Pyongyang, where the Ryugyong Hotel — a reinforced-concrete pyramid one hundred and five storeys tall, built without structural steel because North Korea lacked it — has stood since 1987 with three thousand rooms that have never held furniture and five revolving restaurants that have never served a meal, its shell standing windowless for sixteen years before Egyptian engineers clad it in glass for a hundred and eighty million dollars, its interior still exposed cement as of the only known photographs from 2012. You descend to Mineral Wells, Texas, where the Baker Hotel opened in 1929 with four hundred and fifty rooms, a hydraulic ice-water cooling system, and an Olympic-sized pool filled with mineral water drawn from a limestone aquifer three hundred million years old — water rich in calcium, magnesium, potassium, and lithium that over a hundred and fifty thousand visitors a year came to drink as medicine, until modern science said it was not medicine, and the hotel closed in 1972 and has not reopened. Then you stand above Tequendama Falls in Colombia, where the Hotel del Salto was built in 1923 opposite a four-hundred-and-thirty-three-foot drop that the Muisca people believed transformed those who leapt into eagles — the hotel closing in the early nineteen-nineties after the Bogotá River that feeds the falls became one of the most polluted rivers in the world, its surface covered in white chemical foam, the mist from the falls carrying the smell of a contaminated city upstream. You climb to one thousand and seventy-five metres on Bokor Mountain in Cambodia, where the French colonial administration opened Le Bokor Palace in 1925 — thirty-eight rooms with Spanish floor tiles and Italian bathroom fixtures at the end of a road that killed approximately nine hundred Khmer prisoners during construction — the hotel abandoned and reoccupied five times across wars, coups, and occupations, its walls still carrying bullet holes from 1979, restored and reopened in 2018 with thirty-six rooms. You learn what concrete remembers — how carbonation lowers the pH that protects steel reinforcement, how freeze-thaw cycling cracks Baltic facades, how monsoon humidity at altitude accelerated spalling at Bokor within forty years — and you consider the pattern: every hotel solved the engineering problem it was designed to solve, and every hotel failed because its premise failed, whether that premise was ideology, pseudoscience, empire, or the assumption that a river would stay clean. The rooms are still there. The concrete holds the shape of every intention. The guests are not coming. And the buildings wait.
