Yes, most of the local community in Negombo are Catholics, but there are also temples for the Buddhists to pay their devotions. The main entrance to the Angurukaramulla Temple takes the shape of a mouth of a dragon and once you enter, you will be able to see several sculptures, paintings, and murals depicting various Buddhist stories and beliefs. Once you are done exploring the temple, just head to the old villa from the colonial times which is located right next to the temple premises. It's an abandoned place, but it's worth a small visit.
