Précontinent II Shaab Rumi became famous in 1963 when Jacques-Yves Cousteau and his project "Précontinent II" began scientific experiments in the field of diving medicine. On the western side of the reef, Cousteau built an underwater village on a small terrace where eight people lived and worked for one month at a depth of 10 metres. Today, the results of this experiment still make an important contribution to offshore (deep-sea) diving. Additionally, the team gathered a great deal of scientific data on the underwater world and shot a documentary film called "Le monde sans soleil" (World without sun). The corall garden on the terrace around the remains of Précontinent is a wonderful place for nightdives.
