The church of Notre-Dame d’Alleaume was built on a site where the remains of the Gallo-Roman town of Alauna have been found. The edifice which was altered in the 13th, and 15th centuries (enlargements) and in the 18th century (re-working) retains some elements of the 12th century (porch in the south wall of the choir, door in the south wall of the nave). The lintel of a door in the south wing of the transept shows an older bas-relief (probably from the mid-11th century). It shows two saints under arches (Peter and John), a down bearing an olive branch and the mystic lamb, an image of Christ. It has not been possible to attribute this rather archaic work to any sculptor of the Romanesque period in the Cotentin region.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.
