Old Pillars under Modern "Jade Garden" (previously "Hazledean") [????- ] | Gwulo: Old Hong Kong

Old Pillars under Modern "Jade Garden" (previously "Hazledean") [????- ]

Current condition: 
In use

Whenever I walk pass this spot on Park Road or Robinson Road and look up, I notice these big old columns on the terrace base of modern "Jade Garden". They are both round and square Greek-style doric columns and quite magnificent looking. I am surprised they are so unknown to most people as I could hardly find any information about them online and the Government has never mentioned them in anything. Hope Gwulo readers can give me more information about this (especially its date of completion, the current one is just a guess) and make this place get the recognition it deserves!
