From a Cereal Magazine online article (March 2, 2020):
Of all Gio Ponti’s 100-odd buildings, Sorrento is the only hotel where you can still stay, fully immersed in his art — for as well as the building itself he designed every last detail. He was not just an architect, but a designer — of interiors, furniture, industry, cars — an artist and a ceramicist, a writer and a teacher; and at Parco dei Principi his passion for so many disciplines converged in one triumphant paean to modernity.
The concept of infinite blue was architect Gio Ponti’s driving inspiration when he built Parco dei Principi, his slice of 1960s modernism on a coast of faded antiquity. When it opened in 1962, the hotel was something new for ancient Sorrento: a clean-lined, contemporary edifice on the tufa-stone cliff. Inside, the bright, wide-open spaces were pared down and decorated entirely in white and blue.
