La Salle College (LSC; Chinese: 喇沙書院, Mandarin pinyin: Lǎshā Shūyuàn, Cantonese jyutping: laa3 sa1 syu1 jyun2 ) is a boys' secondary school in Hong Kong. It was established by the Brothers of the Christian Schools, a Roman Catholic religious teaching order founded by St. Jean-Baptiste de La Salle. La Salle College is one of a limited number of schools in Hong Kong that teach in English. The school curriculum uses English as the medium of instruction in all subjects with the exception of Chinese-related subjects and French. In 1917 the Brothers of the Christian Schools, who had founded St. Joseph's College in 1875, opened a junior school on Chatham Road near the Rosary Church. At this time Kowloon was expanding rapidly. The demand for schools was rising and Brother Aimar Sauron, the Director of St. Joseph's, realized that a new school building was necessary. He acquired a large plot near Prince Edward Road as a site for the new La Salle College in 1928. The site was immediately north of the city boundary, and thus was technically in New Kowloon. That section of Boundary Street was not yet a formal road when the school site was bought, and was only gazetted in 1929.
