Stroll around in Pothia, the amphitheatrical capital of Kalymnos with the picturesque passageways and colorful houses that sprawl over the edge of two opposite hills, and admire the neoclassical mansions with Italian traits, the captains’ houses, but also the humble homes of sponge divers.
In Pothia there is also the New Archaeological Museum, where findings from the prehistoric to the post-Byzantine era are exhibited, of which the most important is the bronze statue of the "Lady of Kalymnos", a great example of sculpture of the Hellenistic period.
The Metropolis of the Transfiguration of the Savior (1861) dominates the waterfront of Pothia. Its marble altar was crafted by the great sculptor Giannoulis Halepas from the island of Tinos.
Kalymnos has a centuries-old tradition of sponge diving. On the waterfront of Pothia you will find natural sponge workshops where you can see the traditional processing method and buy your own natural sponge. To learn more about the history of Greek sponge fishing, visit the Maritime Museum of Kalymnos.
Between Pothia and Chora is the medieval Castle of Chrysocheria, built in the 15th century by the Knights Hospitaller. A few meters from the castle three stone windmills stand to this day.
On the eastern side of the island you’ll find Vathy, a small, evergreen settlement that resembles a fjord, as the sea enters a fertile valley with citrus fruits, forming the port of Rina.
Take a walk in Chora and stand in the church of Agios Savvas. Standing in the courtyard, marvel at view of Pothia valley.
Next to Chora, stands the most important ancient place of worship on the island, the Sanctuary of Delian Apollo, who was an Olympian god and the protector of ancient Kalymnos.
Visit the Cave of Kefalas or Cave of Zeus, with its 103-meter-long corridor and impressive stalagmites and stalactites.
