Jamaica joins the rest of the world today, April 18, in observing International Day for Monuments and Sites under the theme, the “Cultural Heritage of Water”. This observation couldn’t come at a more opportune time considering the controversy developing over one of Jamaica’s popular blue holes, the Blue Lagoon in Portland. The Blue Lagoon is a 55 m (180 ft) deep extinct volcano, surrounded by lush tropical foliage, fed by underground streams. It is very popular with swimmers and divers. It is in fact the largest of Jamaica’s spring-fed lagoons.
