Lazaros Koundouriotis Mansion (National Historical Museum)
Lazaros Kondouriotis
Called the “Father of the Nation,” Lazaros Koundouriotis was great shipowner who played an important role in the Greek War of Independence. Located near Hydra’s port, the archontika, or manor, of Lazaros Koundouriotis provides a superb example of the eighteenth-century Hydriot mansions facing the harbor, whose architecture often reflects influences from abroad. Built in 1780, it was donated to the Historic-Ethnologic Institute of Greece by the family’s descendants and today operates as a branch of the National Museum of History. (more…)
