Horsburgh Lighthouse

Horsburgh Lighthouse was named after Captain James Horsburgh (September 28, 1762 – May 14, 1836), a Scottish hydrographer from the East India Company, who mapped many seaways around Singapore in the late 18th century and early 19th century. He was called "The Nautical Oracle of the World". His charts and books allowed ships to navigate through treacherous areas of the ocean, saving many lives and property on the seas between China and India. 
The lighthouse was built over an outcrop of rocks that for centuries was identified on maps as Pedra Branca (white rocks in Portuguese). It was built by John Turnbull Thomson (1821–1884), a government surveyor. In the presence of Governor William John Butterworth and other dignitaries, the lighthouse foundation stone was laid on May 24, 1850 and the lighthouse was completed in 1851. The lighthouse is also known as Pedra Branca Lighthouse.

Horsburgh Lighthouse was a familiar sight to me for 15 years whilst I was in the Navy. It was where the infamous Patrol sectors were drawn during Operation Thunderstorm, during the Vietnamese refugee patrolling days.
