On 24 September 2015, Sri Lanka issued a stamp to celebrate World Maritime Day. Just to the left of the bow of the container ship pictured on the stamp we see a red and white banded tower which is the Colombo East Breakwater Light. It is dwarfed by the much larger Colombo Pilot Station which was completed as part of the port expansion in 2013.
