Cathedral of Hydra

The cathedral is located behind the marble clock tower in the center of Hydra Harbor

Originally constructed in the mid-1600s and rebuilt in 1750 by Venetian architects following an earthquake, this Byzantine-style cathedral with its two marble bell towers consists of a three-laned, pillared basilica with cupola and a marble temple. Its magnificent interior includes a marble iconostasis, hundreds of gold and silver icons, and other elaborate Orthodox decoration. (more…)

Hydra’s Architecture
Stone windmills, some in ruins, dot the hillsides, and the town and surrounding villages are home to more than 350 churches and chapels. Hydra’s status as a national historic landmark protects its unique and beautiful architecture. Any new buildings must stay in keeping with the island’s historic architectural style, using authentic colors and maintaining the traditional Hydriot character. As a result, no modern building developments (high-rise apartments, hotel complexes) can spoil Hydra’s traditional atmosphere. In addition to cars and mopeds, neon signs have been banned. Hydra’s architecture, which includes simple houses as well as grand manors, is unique to the island. (more…)

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…)
