That was the miracle Waglan Island offered the shipping world when its lighthouse entered service on 9 May 1893 — a mercury bath rotating system so finely balanced that almost no force was required to keep the massive first-order lens turning through the night. The technology came from the Paris workshop of Barbier, Bénard & Turenne, and Waglan was one of only two places on Earth where it debuted simultaneously. The other twin lens went to Beiyushan Lighthouse. Both were built for the Chinese Maritime Customs Marine Department, then shipped in pieces — cast iron sections packed for a sea voyage — to be reassembled on their respective rocks. On Waglan, that rock sits at the southeastern tip of Hong Kong, where the South China Sea opens wide and the approach lanes to the colony's growing harbour demanded a dependable fixed light.
