Run by one of Sri Lanka’s more politically adept monks, Galboda Gnanissara Thera, this bustling temple complex has a library, a museum and an extraordinarily eclectic array of bejewelled and gilded gifts presented by devotees and well-wishers over the years (plus one lonely and chained temple elephant named Ganga). Gangaramaya is the focus of the Navam Perahera on the February poya (full-moon) day each year. This is the centre for the most extravagant Vesak celebrations in Colombo.
