The port of Valletta stretches along the water's edge and the historic quay wall, and was used by the Knights of Saint John and European merchants to unload their wares. The old, decadent power station stands as a testament to the port's eclectic and heroic history dating back to 1626. It is also worth noting that the Port of Valletta welcomes over half a million open-air passengers, as one of the world's most successful seaports.
