The Ancient Acropolis, Paleokastro, on the island of Nisyros

Paleokastro, the classical and Hellenistic Acropolis of Nisyros, is an archaeological marvel that offers a glimpse into the island’s ancient past. Perched on a hill overlooking the village of Mandraki, this ancient fortress complex was constructed between the 6th and 4th centuries BC. It is renowned for being one of the best-preserved examples of its kind in the world, showcasing the architectural ingenuity and defensive strategies of ancient civilizations.

Architectural and Historical Significance

Paleokastro is a striking example of classical and Hellenistic fortification, with its massive walls and towers constructed from enormous black volcanic slabs. These slabs are not only impressive for their size but also for their precision in fitting together. The walls, built from these enormous stones, demonstrate advanced engineering skills; some slabs are up to 3.5 meters in width and weigh between 3 to 4 tons each. The interlocking nature of these stones reflects the sophisticated construction techniques employed by the builders.

The fortress complex features six well-preserved towers on the southern side, accompanied by a substantial 230-meter-long wall. On the eastern side, two additional towers and 80 meters of wall remain intact. The defensive architecture includes sophisticated systems for communication and observation. The ancient defenders used smoke signals during the day and fire signals at night to maintain contact with other fortifications and settlements, ensuring coordinated defense and alert systems.

Defensive Features and Structures

Paleokastro’s design was meticulously planned to ensure robust protection for its inhabitants. The walls were constructed to encircle the city within, which remains largely unexcavated but hints at the complexity and importance of this ancient settlement. The fortress is notable for its massive stairs, which consist of 15 and 18 steps respectively, leading to the walkways atop the walls. These walkways, preserved to a height of 7.5 meters, provided strategic vantage points for defenders and contributed to the fortress’s formidable defense system.

While some stairs further along the walls are less well-preserved, those near the entrance remain in excellent condition, offering insights into the original construction techniques. On the southern wall, significant restoration work was undertaken during the Hellenistic period to repair and enhance a tower and a flight of stairs, showcasing the ongoing importance of the fortress through different historical eras.

The fortress’s sole surviving gate, measuring 2.10 meters wide and 3.20 meters high, is a notable feature. Positioned in a recess that faces one of the towers, the gate was strategically designed to allow defenders to fire upon attackers while remaining protected. This design highlights the fortress’s tactical considerations and its role in the island’s defense network.

Restoration and Preservation

In recent years, extensive restoration efforts have been carried out at Paleokastro to preserve and maintain its ancient structures. After a thorough study of the stone blocks and their original positions, many of these blocks were carefully reinserted to their original locations. These restoration efforts have been crucial in maintaining the site’s historical integrity and ensuring that future generations can appreciate and study this remarkable ancient acropolis.
