Universal Studios Singapore Universal Studios Singapore (; Tamil: யுனிவர்சல் ஸ்டுடியோஸ், சிங்கப்பூர் ) is a theme park located within Resorts World Sentosa on Sentosa Island, Singapore. It was a key component of Genting's bid for the right to build Singapore's second integrated resort. On 8 December 2006, the Singapore government announced that the consortium had won the bid. Construction of the theme park and the rest of the resort started on 19 April 2007. It is the second Universal Studios theme park to open in Asia (Japan being the first), and the first in Southeast Asia. The official plans for the park were unveiled to the public when Universal Studios Singapore released a park map to the public on 20 October 2009. Universal Studios Singapore has since attracted more than 2 million visitors in the 9 months from its opening.
