The castle of Chlemoutsi is known around Greece as the most well preserved medieval castle of the country. It is located 50km north of the port of Katakolo and by car the trip to there takes about 40 minutes.

Its massive fortified walls and main tower are visible from far away. From the hill you can have a panoramic view of the surrounding area and you can spot the Ionian islands of Zakynthos and Kefallonia on the west and the Erymanthus mountain range on the east.

Chlemoutsi was built by the frank Geoffrey I of Villehardouin, crusader knight and ruler of the area, around 1220 to be used as his main stronghold. It marks the era when a big part of western Peloponnese was under frankish rule.

Around Chlemoutsi is built the traditional village of Kastro (Castle) and on the footsteps of the hill is the seaside village of Arkoudi and the hot spa of Kyllene.
