These caves are on the coast to the south of Mombasa, in front of the landing stage from where boats set off for the island of Wasini. The site does not have a glorious past, because in the 17th and 18th centuries these caves were used to hold slaves before they were sent, for the most part, to Tanzania. The captives were sent down into the caves via a ladder which was then removed to stop them from getting out, and they would not see daylight again until they left the country through a hole in the rock eroded by the sea. Some captives would even drown during particularly high tides. Today, bats have made the caves their home.
