A man swalk past a sign post at the former prison known as Tekunle on Ita Oko Island outside of Lagos, Nigeria. The prison is cut out of the dense jungle that engulfs this island outside of Nigeria's largest city, but it never officially existed although many critics of the nation's military rule were kept here. Ita Oko Island allowed Nigeria's military governments to have opponents disappear into the swamps of the Lekki Lagoon at a camp accessible only by boat and helicopter.

A pedestrian walks past a traditional colonial-era Board House dating back about a century on Pademba Road in Sierra Leone's capital Freetown on April 27.
