Chlemoutsi (Greek: Χλεμούτσι or Χλουμούτσι Chloumoútsi), also known as Clermont, is a medieval castle in the northwest of the Elis regional unit in the Peloponnese peninsula of southern Greece, in the Kastro-Kyllini municipality.
It was built in the early 1220s by the Crusader rulers of the Principality of Achaea as their main stronghold and is perhaps the finest fortification of the early period of Frankish rule in Greece preserved in the country today. The castle is located on a small plateau 226 metres above sea level and comprises a central hexagonal keep built around an inner courtyard and containing two-storeyed halls along its entire length, and complemented by an outer wall enclosing an outer yard on its western side. The castle is largely preserved in its original 13th-century state, with only minor later modifications for the installation of artillery.
Located near the Principality's capital of Andravida and the chief port of Glarentza, Chlemoutsi played a central role in the Principality's history but was never actually besieged. After coming under Byzantine rule in 1427, it was captured in 1460 by the Ottoman Empire, along with the rest of the Byzantine Despotate of the Morea. In Ottoman times, minor additions were made to provide platforms for artillery, but the castle progressively lost its significance and was completely deserted by the late 18th century. In 1825, during the Greek War of Independence, part of its outer wall was demolished to prevent the Greek rebels from using it. Today it is a preserved monument open to the public.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
