St Andrew's Church was designed by Lieutenant Colonel Ronald Macpherson, and remains one of the few surviving structures of English Gothic architecture in Singapore. Consecrated in 1861, a crew of convict labourers was largely responsible for the construction of the church, which is also the oldest Anglican church in Singapore today. Prior to the fall of Singapore during World War II, the cathedral and its grounds were employed as a field hospital; it was gazetted as a National Monument in 1973.
