Several excavations were conducted during the last century and they brought to light the follows:

Ceramics of the firsthellenic period or the 3rd millenium BC in Agia Marina. Protobyzantine, Paleochristian churches in Baltiza. A Byzantine settlement in Zogeria.

The bronzeage shipwreck of Dokos (2.200 BC), considered to be the oldest known in the world. The Mycenaean shipwreck of Iria (approx. 1200BC).

The procedure of cleaning and restoring the findings, a minute and difficult work that requires patience and time, takes place in specially arranged rooms of the Museum of Spetses, the safest and best organized museum in the region.
