" Horsburgh Lighthouse, located at the eastern entrance to the Singapore Straits, is the oldest of the four lighthouses in Singapore waters. Situated on Pedra Branca, an island 54 km off the mainland of Singapore, it is the first lighthouse in Southeast Asia to be built in granite masonry.  The lighthouse is named after eminent navigator and hydrographer, the late Captain James Horsburgh, and has been in operation since 15 October 1851.  "^^<http://www.w3.org/2001/XMLSchema#string>
