Ithaa, which means mother-of-pearl in Dhivehi, is the very first undersea restaurant in the world located 5 metres (16 ft) below sea level at the Conrad Maldives Rangali Island in Alif Dhaal Atoll in the Republic of Maldives.[1] The 5-by-9-metre (16 by 30 ft) mostly acrylic structure has a capacity of 14 people and is encased in R-Cast acrylic with a transparent roof offering a 270° panoramic underwater view.[2] The restaurant was designed and constructed by M.J. Murphy Ltd. - a design consultancy based in New Zealand - and was opened on April 15, 2005. Food served in the restaurant has evolved over the years and is now best described as contemporary European with Asian influences.

Ithaa's entrance is a spiral staircase in a thatched pavilion at the end of a jetty. The tsunami which followed the 2004 Indian Ocean earthquake topped at 0.31 metres (1 ft 0 in) below the staircase entrance, and caused no damage to the restaurant.

In April 2010, to celebrate the restaurant's 5th anniversary, it was made possible to sleep in Ithaa for the night if the restaurant is not booked for dinner, however this is was a one-year promotion and the "underwater suite" is no longer available.[3] The restaurant is also used for private parties and weddings.[4]


In February 2004, M.J. Murphy Ltd. was approached by Crown Company in the Maldives to make a unique underwater restaurant. The Crown Company, owner of Rangali Island, leases the island to Conrad Maldives Rangali Island (previously known as Hilton Maldives Rangali Island Resort & Spa). Initially Crown envisioned the underwater restaurant with straight walls and glass windows. Later they came to favor Mike Murphy's (of M.J. Murphy Ltd.) R-Cast acrylic tunnel, manufactured by Reynolds Polymer Technology, Inc. in the United States. This tunnel was also designed for the Kuala Lumpur National Science Centre, the world’s largest aquarium tunnel.[5]

Work on technical designs and drawings for Ithaa started in March 2004. Murphy initially planned to build the structure on the beach of Rangali. Once constructed, Ithaa would be winched into the water. Technical challenges, limited resources, and quality control problems in building a structure of 175 tonnes in the Maldives were foreseen. Hence, a decision was made to build Ithaa in Singapore instead.


In May 2004, its construction began in Singapore. In October 2004, the construction work was completed including the installation of 5-metre (16 ft) wide acrylic arches, air conditioning and electrical ducts.

On November 1, 2004, Ithaa was lifted onto an ocean-going barge to be transported to the Maldives, which took 16 days to arrive. At this point, Ithaa weighed 175 tonnes.

On November 19, 2004 Ithaa was "sunk" with the help of 85 tonnes of sand ballast loaded into its belly. It was precisely maneuvered onto four steel piles which had been vibro-hammered 4 to 5 metres (13 to 16 ft) into the seabed. It was then secured to the steel piles with concrete.

The estimated life span of the restaurant is 20 years.

The Hotel[edit]

The hotel (which at the time Ithaa was built was still called Hilton Maldives Resort & Spa) occupies two private islands, Rangali and Rangalifinolhu joined by a 500-metre (1,600 ft) footbridge.[6] It has seven restaurants including the Ithaa Undersea Restaurant.[7][6]
