The National Gallery of Singapore, formerly known as St. Joseph's College (St Joseph's Institution), is a well-known local boys' school. The gallery opened in 1996 and houses more than 400 artworks, the largest collection of local and modern Southeast Asian art in the world. Whether it is exhibition size, all-weather and modern equipment of the video gallery, it is the leading art gallery in Southeast Asia. It is the oldest museum in Singapore, but it contains the youngest and most creative ideas. The biennial Singapore Biennale is a global art event hosted by the National Gallery of Singapore.
