The Spetses Museum is housed in the mansion of Hadjigianni Mexi was built between 1795 and 1798 in the shape of a P and consists of a ground floor and two floors. Decorated galleries on the facade of the building – the ground floor are supported by pillars, the floor in thin pillars – make the heavy architecture lighter. On the ground floor are the private Mexi apartments: the office, the dining room, the room with the safe. On the first floor, the two spacious rooms that served as women’s hostels and hostels, and in the second the typical single space of the Spetsi home, the “big ons”, with an excellent wood-carved ceiling. The objects exhibited at the Museum represent more than 4,000 years of cultural history on the island. The archaeological collection was recently enriched with the generous offer of coins and numerous finds of various periods that Adonis Kyrou has gathered from all parts of the island as well as from other regions. From the meditation, but also from donations, a significant number of icons and various ecclesiastical species come from.

The ceramic items found in another room of the Museum bring to mind the bold trips of the Spetses to East and West in the late 18th century.

The Flag of the Revolution, the busts of Bouboulina, the portraits and the weapons of the same and other fighters, historical documents, personal objects, pictures of ships are testimonies of the contribution of the island to the heroic struggle of 1821.

Last but not least, the objects of everyday use, as well as those of domestic and naval carvings (chests, furniture, acropolis), costumes and embroidery, which are found in various rooms of the Museum, are precious for the way of life of the residents before and after the Revolution.
