The fort of Sao Jao Baptista was finished in 1795 and was restored after a fire in 1813. Now the Association of Friends of the Island has returned to restore to open its doors to a growing tourism. The facilities are small, but the important thing is the story that keeps. Get a good guide from the Ibo you count from the abuses of the Portuguese and the era of slavery or the release of Frelimo. Great views.
