500 metres west  of the southern tip of Slave Island in Western Bay is a small island called Twin Rocks, or Marzuk Kabir. A local legend suggests this is where Noah's Ark was built.  This island never appears to have been built on but a map dated in the 1960's shows a jetty on the southern side

Twin Rocks in 2006

To the southwest of Twin Rocks, Jerama Rock was a very small outcrop located just 200 metres off Hedjuff, outside French Bay. It does not appear on recent satellite images so one might assume it was removed as a shipping hazard.

Round Island or Denafah as it was known locally, is in Round Island Bay on the southern side of the crater some 150 metres from shore. Nothing is presently known of the history of this small island.

An article in a Naturalist magazine says Aliyah Reef in Western Bay was the site of the old cholera quarantine station.
