Sleep next to coral reef and watch marine life creep by before bedtime in the new Manta Underwater Room off Pemba Island, Zanzibar. Although underwater rooms do exist in places such as the Maldives and Stockholm, this is the first one in Africa, and Pemba is renowned for being a great diving spot with a plethora of sealife found in the surroundings waters. Located 250 metres off the coast of Pemba Island, the Underwater Room forms parts of the Manta Resort, a holiday retreat on the mainland of the island, and comprises a three-storey floating structure with its lowest level positioned four metres beneath the water. Coral is expected to grow around the outer walls, plus underwater spotlights are fitted below the windows to encourage squid and colourful sea slugs to come into view. The structure was designed and built by Swedish company Genberg Underwater Hotels and takes its cues from Utter Inn, a floating structure on Lake Malaren in Sweden that was modelled on a traditional Scandinavian house.
