Two Alternative Strategies for the Integrated Restoration of the Central Rectangular Tower of the Eastern Curtain Wall of Larissa Castle in Argos, Greece

Abstract

Larissa Castle of Argos in the Peloponnese represents one of the most significant fortified landscapes in Greece, reflecting architectural transformation and military adaptation from prehistory to the twentieth century. Amongst its parts, one of the best-preserved towers has recently regained much of its original form through partial restoration works, emerging as a dominant landmark within the castle and the wider Argolic landscape. This study investigates the complete restoration and adaptive reuse of the tower, focusing on the challenge of providing public access while respecting its historical and architectural integrity. Based on detailed architectural analysis, two alternative design approaches for vertical circulation and access to the battlement level are examined. The first proposal employs traditional materials and construction principles, whereas the second introduces a contemporary intervention through a lightweight metal spiral structure. The comparative assessment demonstrates how both solutions can facilitate visitor access, enhance the interpretation of the monument, and reveal the tower’s defensive operation and architectural evolution, while respecting the construction phases of the monument and the international principles of cultural heritage. The proposed reuse as an observation point capitalizes on the tower’s strategic position and exceptional panoramic views over the major archaeological landmarks of the Argolic plain. The original contribution of this study lies in the systematic comparison of two evidence-based intervention strategies—one historically referenced and one explicitly contemporary—within a common conservation framework applicable to similar defense monuments.
