- Pedra Branca (meaning White Rock in Portuguese) is a pile of rocks situated where the Singapore Strait meets the South China Sea, measuring at its longest, during low water spring tide, a mere 137 m. It has a land area of 0.2 hectares.
- It was recorded as early as 1583, by the Dutch voyager Johann van Linschoten, that Pedra Branca is where ships that come and go to and from China pass in great danger and some are left upon it.Between 1824 and 1851, at least 25 sizeable vessels came to grief on those rocks.Even recently, from 2000 to 2004 there were 2 reports of ship collisions.
- In 1851, a lighthouse was built and was named Horsburgh, after a Scottish captian who mapped the waters of the area.
- The island is disputed by Singapore and Malaysia. Malaysia only placed Pedra Branca into her maps only in 1979.
