Rhodes Aquarium is located at the northernmost edge of the island and offers visitors the chance to have a close-up view of the marine life of the Eastern Mediterranean. It was built in 1930s and is currently administrated by the National Center of Marine Research. The Aquarium is housed in a very interesting building, designed by the Italian architect Armando Bernabiti. It started to operate in 1937 with the name “Reale Istituto di Ricerce Biologiche di Rodi (Royal Biological Research Institute of Rhodes)”. Apart from being an aquarium, it has been operating as a research center and a museum since 1963. Its research activities include oceanography, hydrology, sponges and fisheries of the Aegean. However, the main object is to exhibit a comprehensive collection of live marine organisms.
The Aquarium is located at the basement of the Hydrobiological, Station and has been fashioned in the form of an underwater sea cave. It features a corridor with 40 tanks filled with a total capacity of 75000 liters (21,000 US gal) of filtered seawater. The tanks are home to several specimen of Mediterranean organisms such as reefs, sea flowers, turtles, crabs, urchins, dolphins, sea anemones and a large number of fish.
