D. S. Senanayake College

In 1965, the number of requests to admit children into the Royal College Primary had become excessive. Thus the Minister of Education I. M. R. A. Iriyagolla took the initiative to build a new school in Cinnamon Gardens on the lines of Royal College, Colombo.^[4] In 1967, Iriyagolla began the ground work for establishing the school. It was named after D. S. Senanayake, who was the first Prime Minister of Sri Lanka (then Ceylon) after gaining independence. R. I. T. Alles, an assistant principal at Royal College became the head teacher of the new school. The location where the college stands today was at that time called the Kumbikale jungle.^[5]

As a resolution the Ministry of Education had taken a decision to increase the number of primary schools, to meet the increasing demand of parents enrolling their children to Colombo schools. The secretary of the Ministry of Education and Cultural Affairs, M. J. Perera, was assigned to find a suitable plot of land to start the new school. Accordingly, the empty plot of land situated down the Gregory's road normally "Kubi Kelle" adjoining Kinsy road was selected for the purpose with another land bounded the said premises which belonged to the Ministry of Defense and also was acquired building plans were prepared and implemented by the state engineering co - operation.^{[citation needed]}

Alles who had been an assistant teacher at Royal College had been appointed as the principal of D. S. Senanayake College. He was helped by the principal of Royal College, B. Premarathne. The cadet platoon of the Royal College also cleaned the land holding a shramadana. Five assistant teachers and office equipment were donated by the Royal College.^{[citation needed]}

The school has a hostel which provides accommodation to over 200 students. The hostel was opened in January 2003 by the Minister of Education, Karunasena Kodituwakku. The students were admitted to the hostel for the first time in February 2003.

Senanayakians were the first to establish a War Heroes’ Monument within the premises of a school. About 33 old Senanayakians sacrificed their lives during the civil war. ^[6]
