Chysauster Ancient Village (meaning Sylvester's house) is a late Iron Age and Romano-British village of courtyard houses in Cornwall, which is currently in the care of English Heritage. The village included eight to ten houses, each with its own internal courtyard. To the south east is the remains of a fogou, an underground structure of uncertain function.
Chysauster village is believed to have been inhabited from about 100 BC until the 3rd century AD. It was primarily agricultural and unfortified and probably occupied by members of the Dumnonii tribe. The village consists of the remains of around 10 courtyard houses, each around 30 metres in diameter. Eight of the houses form two distinct rows, and each house had an open central courtyard surrounded by a number of thatched rooms. The houses have a similar layout. The buildings are oriented on an east-west axis, with the entrance facing east. The walls survive to heights of up to 3 metres. A field system in the vicinity attests to the site's farming connections.
To the south of the settlement is an underground passage of a type known locally as fogou (from the permanently lenited form of mogow, Cornish for cave). Fogous can be found in other places in the UK and Ireland, and are known more generally as souterrains; their purpose is unclear. The fogou at Chysauster was originally recorded as running well over 16 metres in length but was blocked up in the late 20th century for safety reasons.
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.
