Known to be one of the largest cathedrals in the country, the beautiful St. Mary's Church is located in the very heart of Negombo. Featuring cream-yellow walls and contrasting black and white marble detailing, St. Mary's Church is certainly a sight to behold. During the day, the interior of the church is stunningly lit by the daylight streaming through its stained-glass windows. Some key feature, to take in while visiting this 140-year-old church apart from the stained-glass windows, and intricately decorated ceilings is the magnificent church organ. Do note that photography is strictly prohibited within the church. To take part in the early morning prayers, consider visiting around 7-8 am.
