The Diyatalawa Garrison is a common name used for collection of military bases of the Sri Lanka Army located in and around the garrison town Diyatalawa in the Uva Province. Sometimes it is referred to as the Diyatalawa Cantonment. It is one of the oldest military garrisons in Sri Lanka. It is home to the several training centers of the army, including the Sri Lanka Military Academy and has a detachment of the Gemunu Watch. The Sri Lanka Army Medical Corps maintains a base hospital in Diyatalawa. SLAF Diyatalawa is situated in close proximity.
It is not exactly known as to when Diyatalawa became a training station for troops, but available records show that it was selected around 1885, when the British Army first established a garrison at Diyatalawa. At that time training was conducted at the Imperial Camp which is presently occupied by the Gemunu Watch troops. In 1900, the British War Office constructed a concentration camp in Diyatalawa to house Boer prisoners capt
