This is a private museum, a life's work of Valsamidis brothers, who were born and live in Kalymnos. Their love for the sea and the willingness to share its joys and wealth with other people, lead them build this museum with enormous personal effort and enthusiasm. The result of their work will impress you.

The findings, which have been collected after thousands of divings in the sea all around the world, include almost anything that can be found on the seabed; fish, shells, shellfish, starfish, corals, sharks, turtles and tortoises, and of course all kinds of sponges.

Part of the museum is dedicated to the profession of sponge collectors. In these rooms you will see the tools and diving suits that were used by scuba divers from 1872 until today.

In a separate wing findings of the WWI and WWII are exhibited, such as torpedoes, pieces of planes etc while in a specially designed area jars of 6th, 4th, 3rd and 2nd BC century are being kept.

In the museum there is also a collection of about 2000 photographs that demonstrate the history and the traditions of the sponge collectors. In the museum you will also witness the sponge processing and you may find nice souvenirs such as sponges, corals and shells in the store that operates within.
