A gorgeous ruin lying truly abandoned in the middle of small-town Cuba, that's heavy with atmosphere and still shines (despite the mildew) with a perceptible beauty. Between the 1920s and 1950s, this grand edifice functioned as an expensive bathhouse and hotel. These days it hosts birds nests, weeds and – who knows? – the ghosts of guests past.
There's no entry fee and barely any other visitors. Just slip inside and enjoy the magic on your own while you still can.
