The Temple of Poseidon was built in Doric style about 520 b.C. The stones
were porous limestone from Aegina. The temple was destroyed in a big
earthquake around 395 A.D.
The systematic excavations started 1894 by the swedish archaeologists
S. Wide and L. Kjellberg. It is very difficult to get a complete picture of
what the temple looked like, and that is because of the total destruction
of the place. From 1760 the wealthy people of Hydra used this place as a
quarry when building their houses.
Demostenes, the famous greek orator, drank poison and died here.
He was to be thrown in prison, but refused to submit.
