As a very young man he took part in the expedition of the Argonauts and he had a very long life, because he was still active after the Trojan war. The resourceful Palamides is considered to be the son of Nauplius. Palamides when became the king of Nafplio, joined Agamemnon at the Trojan war and with the king Ulysses of Ithaca, were the smartest ones of the army. The castle, named after him was designed by the French engineer Lassalle and built at 1705 AD. It has 7 towers and in order to go up there, one has to climb 999 steps. The construction was financed by Venetians, at the high economic pick of Venice. Venetians conquer harbors from the Turks, build castles in order to secure their dominion and practice duty free trade, without paying any port authorities. This is the reason for the enormous wealth they gathered in Venice on one hand and on the other hand for the big number of their castles all over Greece.
At 30 of November 1821, during the Greek war of independence, Staikos Staikopoulos got first in the Palamidi Castle.The Turks never re-conquered it. In 1828 Nafplio became the capital of the newly constituted Greek state until 1834, when the capital was transferred to Athens.
The town of Nafplio hosts some very interesting museums, like the one of Folk Art and the Archaeological museum, which is housed in the very impressive building of the Venetian Hospital. In it, the admirable collection of Mycenaean ceramics is kept, part of which is a unique clay wine-cooler and one also unique Mycenaean armor.
