Located at Mount Sophia for more than a hundred years since its founding in 1887, Methodist Girls' School moved to its current location at Blackmore Drive in 1992. Realising the need for girls' education in Singapore, Reverend William Oldham, the founder of Anglo-Chinese School, requested the Women's Foreign Missionary Society to send a woman volunteer for this cause. As such, Sophia Blackmore, an Australian missionary, arrived in Singapore in 1887 and subsequently founded the school. It was the first educational institution for girls established in Singapore by the Methodists. It started as the Tamil Girls' School (1887) and was later renamed Methodist Mission Girls' School in the 1890s and during WWII, it was known as the Mount Sophia Girls' School.
