the Main Atrium. It houses the Year 1-4 General Office and the Raffles Archives & Museum. Major upgrading works were completed in early 2007. Science Hub The Science Hub, opened in 2008, includes facilities for specialised research such as Xploratory-Labs; as well as Chemistry, Physics and Biology labs. It also houses the Discovery Labs, a Laser Animation/Technology Studio, the Materials Science Lab and the Raffles Academy Home Room. It is connected to the Yusof Ishak Block. Hullett Memorial Library / Shaw Foundation Dining Hall The Hullett Memorial Library (HML) stands between the Sheares Block and ArtSpace. Co-founded by Lim Boon Keng and Song Ong Siang, it was named after RI's longest-serving Headmaster, Richmond William Hullett, in 1923. The library's official founding (even though a library and museum, from which the National Museum originated, had existed for decades prior to 1923) also marked the centenary of the founding of the institution. The library traces its roots to the founding of RI, making it the oldest library in Singapore. The origins of Singapore's National Library lie in the HML. Sports facilities The school's gymnasium underwent renovation in 2010, and was used as a training venue for gymnasts during the 2010 Summer Youth Olympics, together with that in the Year 5-6 campus. The school also has two tennis courts, two basketball courts, two squash courts, and two cricket nets. Following the re-integration with Raffles Junior College from 2009, more sports facilities are available. Floorball, table tennis, judo and gymnastics are RI sports now able to use the Year 5-6 Campus facilities.
