In this effort, they built the first fortifications with the help of the Normans, initially in the 11th century by the residents of Parga to protect their town from pirates and later the Ottomans.

The town and its castle were unsuccessfully offered by Nicholas Orsini, the Despot of Epirus, to the Republic of Venice in exchange for Venetian aid against the Byzantine Empire.

[5] In 1452, Parga and the fortified position was occupied by Hatzi Bey[6] for two years; part of the castle was demolished at that time.

An inscription above the outer gate dates the construction of this section wall to 1707 by Count Marco Teotochi, governor and captain of Parga.

[8] In 1792, The Venetians began construction on the third and final fortress, with work being completed in 1808[9] by the French during their stay in the wider area between the years 1797 and 1814.

Ottoman rule in Parga and the rest of Epirus ended in 1913 following the victory of Greece in the Balkan Wars[11] coming under the control of the Greek state.

In this castle, free besieged Parginians and Souliotes fought heroic battles and held their freedom for centuries.

In the arched gate of the entrance, the winged lion of Saint Mark can be seen on the wall, the name "ANTONIO CERVASS 1764", emblems of Ali Pasha, two-headed eagles and related inscriptions.

[12] Vaulted corridors, shooting rooms, supply arcades, strong bastions with firearms, light weapons, it is said that there is still a secret passage to the sea, barracks, prisons, warehouses and two forts on the last line of defence: they show perfection along with the plan they made the natural fortification an invincible fortress.
