This island has given the world Hippocrates, father of medicine; it looks like a huge floating garden. The city is built along a wide bay and catches the eye from the very first moment. Here we shall visit the Knights' Castle, an impressive medieval building, Freedom Square with its huge plane, under the shadow of which Hippocrates is said to have taught, also Roman homes with marvellous mosaics early Christian basilicas and the Museum, with its status of Hippocrates (4th century BC) and other fascinating items of Ancient, Hellenistic and Roman times.
We can also see the doric Temple of Venus, the Roman School of Music and the Castle, built c. 1450-1478 by the knights of St John on the ruins of the ancient wall.
The Castle houses a small collection of Classical scupltures as well as inscriptions of the Hellenistic, Roman, Byzantine and early Crhis-tian period.
Four kilometres to the SE of the city we shall visit the Aesculapium, infirmary of Antiquity, which began to
be built in the 4th century BC. The ground slope is such that buildings exist on four different levels connected by a marble staircase. Among the ruins we can discern the Temple of Aesculapius, the Stoa of Hippocrates' medical school, and the altar.
The island boasts villages well known for their beauty, eg. Asfen-diou (14 km from the city), Karda. maina (by the sea) and Pyli. From Pyli the road leads to Palio Pyli, with remnants of an old castle, and to the fishing villages Marmari and Mastichari. At the southwestern end of the island lies Kefalos, a village endowed with wonderful sandy beaches and little tavernas. In Kefalos, at the Palatia site, we can see the ruins of Astypalaia, capital city of the island in Antiquity.
There is a beautiful beach near the town. There are others - marvellous and often quiet places - all over the island, some of them accessible by bicycle - a means of transport much used in Kos.
