The Manor of George Kountouriotis is located to the west side of the harbour, to the bank of the hill, between the pine trees.

George Kountouriotis, brother of Lazaros, was one of the greatest ship owners of Hydra and got involved with politics during the Greek Revolution and to the years that followed.

In 1824 he elected president of the executive council of Greece and formed his own democratic goverment in Nauplio. He had to resign in 1826.

After the murder of the governor Kapodistrias, to whom Kountouriotis acted argumentative, he elected as President of the Senator and the cabinet council.

The grandson of George Kountouriotis, Paul, inherited the Manor. Paul was a political figure, who also elected Minister of the Navy, captain of the Greek fleet, President of the Hellenic Republic and viceroy.

In 1991 the three stories tall Manor was bought from the Ministry of Culture and then it operated as a Museum.

Inside there are exhibits of family heirlooms and exhibits from the newest history of Hydra.
