[2][3] In 1867 it was taken over by the second Bishop of Colombo, Piers Claughton, and the Anglican Church, and renamed the All Saints English School, with 137 students enrolled.

[4][5][6][7] On 9 January 1959 management of the school was transferred to the state,[4] and later renamed All Saints College.

In November 2017 the government, through the Ministry for Southern Development and the Ministry for Law and Order, issued a directive for the school, and a number of other government institutions, to vacate their buildings in the historic fort precinct by the end of December.

[8] It was then found that the government had not consulted the Department of Archaeology, the Ministry for Education or the Sri Lanka National Commission for UNESCO.

[9] Subsequently the Department of Archaeology and the Galle Heritage Foundation negotiated for the school to remain in the fort.
