In Hong Kong, whose name literally translates to "fragrant harbour", curator Angel Cheung built the hotel's scent around native agarwood, layered with jasmine and warm amber, a quiet nod to the city's old incense-trading history and the hotel's own legacy as its oldest. In Paris, Céline Barel, who grew up in Grasse, the perfume capital of the world, leans into rose damascena and labdanum resin. New York gets something cooler and more contemporary from Mackenzie Reilly—golden quince, peony, musk—while in Bangkok, self-taught curator Prin Lomros distills the Chao Phraya River at sunset into mango, lotus, orchid and a breath of mint. London's note, designed by Timothy Han, a former assistant to John Galliano, is drier and more tailored: ozone, bergamot, pine, teak, built to recall the romance of old-world travel.
