The fort of the Palamidi, which has been preserved in excellent condition, is one of the greatest achievements of Venetian fortification architecture. The hill of Palamidi, which takes its name from the Homeric hero Palamidis, does not seem to have been systematically fortified until the second Venetian occupation. The construction of the fort was basically carried out during the time of Venetian General Superintendent of the Fleet, Agostino Sagredo, from 1711 to 1714, marking the fort not only as a major feat in terms of its fortifications, but also in terms of the speed with which it was constructed. Today, the fort can be accessed either by the road which terminates at the eastern gate or by the famous steps which are located on the western side to the east of the Grimani bastion. These steps are traditionally supposed to number 999, the thousandth having been destroyed by Kolokotronis’ horse. However, in reality there are less and they were constructed during Otto’s reign by prisoners who were held in the Palamidi, under the supervision of the Bavarian army. From here there is an excellent view of the castle of the Acronauplia. Once in the fort one can see, among other things, the imposing bastions, the historic chapel of Aghios Andreas and the impressive water tanks, which even today are used to collect rainwater.

Syntagma Square, the most important and historic square in Nauplion, comprises the centre of the city. It is assumed that from 1540, the time of the first Turkish occupation, the Turkish commander of the Peloponnese, Mora-Pasha, had his seraglio here. The importance of the square is also demonstrated by the number of times it has undergone a change of name. In the 19th century it was known as ‘Platanos Square’ or simply ‘Platanos’, for the plane tree which once occupied the centre, in the shade of which national politicians made speeches. In 1843 the name was changed to ‘Ludwig Square’, in honour of Ludwig, father of King Otto, who had then visited the city. In the same year, after the revolution of 3rd September 1843, when the Greeks demanded that Otto grant them a constitution, the name was changed first to Syntagma (or constitution) Square, then ‘Stratonas Square’, and ‘King George II Square’. Today, one can see many important historic buildings in the square, such as the Venetian Warehouse of the Fleet, which today houses the Archaeological Museum; the parliament, former mosque of Aga-Pasha and finally the Allilodidaktiko School, which came to be known as the ‘Trianon’.
