The town which is the centre of the whole island, is built amphitheatrically around the port.
It looks glamorous like an art-paint, with grey, white and blue colours above the blue of the sea, an exemplar of architectonics and aesthetics. Right and left from the entrance of the port, there are the Parapets with the Canons, which protected the town. At the left side of the port, after the statue of A. Miaoulis, we can find the Harbour Authorities of Hydra, which are accommodated in the old, stonebuilt powder magazine. Next to the Harbour Authorities is the marble Archive Building of Hydra and further we find the house of Tsamados family, which accommodates the famous Sea Captain Academy.
In the interior of the Island have been found traces of ancient living quarters, according to chaeological excavations that took place in the location of “Episkopi”. The first residents of the island where called Dryopes. Hydra was used as a service station for the Greek navy, and as a result, it starred in the sea commerce with neighbouring countries and in communications.
Towards the end of the 18th century, Hydra was bloomming in export trade and commerce. It was that time which people of Hydra took advantage of the English-French war and earned for themselves great profits, by controling the sea commerce. Important was the help of Hydra to the liberation of Greece in 1821. During the war, Hydra was in full alert and ready for battle with the turkish troop.
It had got 130 battleships of 30.000 ton each, 5.400 soldiers and 2.400 cannons. The Captain of turks Hibraim called Hydra “Little England”. The Hydrian fleet dominated the sea during the seven year war with the turks, contributing this way to the liberation of Greece, sacrificing many human lifes, battleships and money. Hydra contributed to the Nation by giving to Greece one President, five Prime Ministers and Ministers. George Koundouriotis, who served as President of the Executive council during the Greek revolution. He was also council member during the Presidency of Kapodistrias and Othonas and also served as Prime Minister and Minister of Navy. Antonios Kriezis, Prime Minister of Greece. Dimitrios Voulgaris, seven times Prime Minister. Athanasios Miaoulis, three times Prime Minister. Petros Voulgaris, Prime Minister.
