The idea for Palamidi to be built had Morosini, Corner and Grimani. The plans were constructed eventually from Grimani, but the work was completed shortly afterwards by Agostino Sagredo. The entire complex consists of eight bastions which are connected with walls and communicate with each other. The fort communicated with the city by two roads, one was covered with a vaulted ceiling and later replaced by a tiered climb with 857 steps.

The fortifications of Palamidi finished within three years (1711-1714). It was the last major achievement in the long history of Enetian domination. A year later, in 1715 Turks with 100,000 troops entered Peloponnese and occupied Palamidi and Acronafplia.

Palamidi occasionally used as a prison of long-term convicted. There was imprisoned Theodoros Kolokotronis, too.
