Penhallam is the site of a fortified manor house near Jacobstow in Cornwall. There was probably an earlier, 11th-century ringwork castle on the site, constructed by Tryold or his son, Richard fitz Turold in the years after the Norman invasion of 1066. Their descendants, in particular Andrew de Cardinham, created a substantial, sophisticated manor house at Penhallam between the 1180s and 1234, building a quadrangle of ranges facing onto an internal courtyard, surrounded by a moat and external buildings. The Cardinhams may have used the manor house for hunting expeditions in their nearby deer park.
By the 14th century, the Cardinham male line had died out and the house was occupied by tenants. The surrounding manor was broken up and the house itself fell into decay and robbed for its stone. Archaeological investigations between 1968 and 1973 uncovered its foundations, unaltered since the medieval period, and the site is now managed by English Heritage and open to visitors.
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.
