The castle is built entirely of stone, deviating from the typical Byzantine practice of incorporating brick layers for structural flexibility.
The central keep contains a massive vaulted hall, which was used for official court ceremonies and banquets.
During the 15th century, the castle changed hands between the Latin rulers, the Byzantine Despots of the Morea, and eventually the Ottoman Empire.
The fortification was specifically designed to be easily defendable by a small garrison, reflecting the precarious nature of Frankish rule in Greece.
The walls include numerous arrow slits designed for horizontal and vertical defense against siege engines.
The structure features a sophisticated rainwater collection system, essential for surviving lengthy sieges in a coastal location.
The Frankish Castle of Chlemoutsi, also known as Clermont, is the best-preserved fortress from the Frankish period in the Morea. Constructed around 1220 by Geoffrey I of Villehardouin, it served as the primary administrative stronghold of the Principality of Achaea. The design features a massive hexagonal central keep enclosed within a secondary outer wall, a departure from traditional Byzantine castle architecture. Its position on the Chelonatas headland provided strategic control over the Ionian Sea and the port of Glarentza. The castle complex houses a permanent exhibition regarding the Frankish presence in the Peloponnese, including armor, coins, and ceramic artifacts. The site remains largely structurally intact, allowing visitors to traverse the interior vaulted halls and the expansive inner courtyard.

Wear sturdy, closed-toe walking shoes as the internal flooring consists of uneven ancient stone and exposed masonry.
Bring a hat and sunscreen, as the castle grounds are almost entirely exposed with minimal shade.
Visit during the shoulder season to avoid the intense heat reflecting off the stone walls.
Attempting to explore the outer perimeter walls without clear signage, as the terrain is rugged and steep.
Operating hours often change seasonally; typically open daily except for specific public holidays and Mondays.
Do not climb on the walls or touch fragile masonry; refrain from sitting on non-public ancient building foundations.
