Gaios is the capital of the island. The harbour is sheltered from the wind and
is shallow and so suitable for smaller boats. The sea is always clean and cool
because of the sea currents. The more northerly part of the harbour, Maneskos,
is deeper. Larger vessels are able to dock here. The name Gaios comes from Agios
Gaios, who brought Christianity to the island. His tomb is in the sanctuary of
the church of the Holy Apostles, where there are some noteworthy frescoes. According
to tradition, soil from the tomb has medicinal properties and can be used in the
treatment of snakebite. The island's most brilliant festival is on 29th June,
when there is a celebration for both the Holy Apostles and Agios Gaios.
