The National Port Authority (NPA) was established by an Act of the National Legislature in 1967 and amended in 1970 as a state-owned corporation to manage, plan, and build all public ports in Liberia. The NPA system comprises four ports: Freeport of Monrovia, Port of Buchanan, Port of Greenville, and Port of Harper.
The Freeport of Monrovia is the largest within the Authority’s network. The harbor at the Freeport of Monrovia is protected by two rock breakwaters approximately 2,300 meters and 2,200 meters long, enclosing a basin of 300 hectares of protected water.
