Blubber Valley, also known as Mosquito Cove, is an official historic site located in the parish of Saint Mary in Antigua and Barbuda. It originally functioned as a sugar plantation that was established prior to 1685.
The site is historically significant for its role in the region's agricultural past. Records indicate that 240 enslaved people were held at the location in 1829. While the original sugar mill tower no longer stands, the area remains recognized as a point of historical interest.
