Dehiwala-Mount Lavinia: History
Before colonisation of the maritime region by the Portuguese, the area covered by the present DMMC was part of the Kingdom of Kotte. It comprised a number of villages such as Pepiliyana Nedimala, Attidiya and Kalubowila, while Ratmalana and areas south of Dehiwala were together one large expanse of marshland, and scarcely populated.
