Where: Pulau Satumu, or One Tree Island in Malay.
What: Singapore's second-oldest lighthouse was built in 1885, using granite from Pulau Ubin.
Where: Pedra Branca, which means "white rock" in Portuguese, is about 40km from the mainland's eastern shore. What: Built in 1851, it is Singapore's oldest lighthouse.
Pedra Branca was at the centre of a territorial dispute between Singapore and Malaysia for almost three decades.
Six years ago, the International Court of Justice awarded Pedra Branca to Singapore.
SULTAN SHOAL LIGHTHOUSE
Where: Sultan Shoal, which marks the western entrance to the Straits of Singapore, near Jurong Island.
What: Singapore's third lighthouse was built in 1896.
Where: On top of a 25-storey apartment block in the Lagoon View condominium in East Coast.
What: It is due to be moved to Block 3, Marine Terrace, in the third quarter of next year.
No reason was given but both locations are unique as lighthouses are typically built on the shore or on rocky outcrops and rarely on apartments.
PULAU PISANG LIGHTHOUSE
Where: On Pulau Pisang, an island about 15km from the Malaysian coastal town of Pontian.
What: It is in Malaysian territory but owned and managed by Singapore. The British government signed a contract with the Johor Sultanate for the right to build and manage a lighthouse on the island.
The right passed to Singapore under international law when it became an independent country.
