December 14, 1866. Tanga region.
Under the scorching sun, the East African colonial administrators in straw hats supervised the indigenous laborers with whips at the construction site.
The indigenous laborers, grouped in fours, slowly moved colossal stones by hand and stacked them at the shoreline.
Immigrants used wheelbarrows to transport sand and cement to the shore, where they mixed it with water to fill the gaps between the piled stones.
This was the newly constructed wharf, made entirely of stone, which had been smoothed and solidified.
Not far off, immigrants and indigenous people used shovels and pickaxes along the coast to widen the bay, with thousands working simultaneously in a grand scene.
This construction site belonged to what would later become Tanga City in Tanzania, and the colonial powers were building Tanga Harbor here.
