The Abbey of Santissima Trinità is a Roman Catholic abbey complex at Venosa. The architecture of the abbey shows Roman, Lombard, and Norman influences. The complex lies within the archaeological park of Venosa.
The date of construction of the monastery is unknown; some elements may date from the eighth century. A foundation date of 954 AD is documented in the spurious Chronicon Cavense of the forger, scholar and priest Francesco Maria Pratilli (1689–1763). Following the Council of Melfi in 1059, the church was transformed from a cathedral to an abbey by a bull of Pope Nicholas II, and the number of monks increased from 20 to 100. In the same year he invested Robert Guiscard as Duke of Puglia and Calabria, and Guiscard made the abbey the religious centre of his domain.
The old church stands on the site of an Imperial Roman building, probably a domus, which shows traces both of earlier Republican occupation and of later Late Classical modification. Some walls of the church are built directly on the mosaic floors of the earlier structure.
To the south of the church and oriented at right-angles to it are the remains of an early Christian basilica, probably built in the late fifth or early sixth century, with a hexagonal font in a trefoil apse.
The Romanesque entrance to the church is flanked by a pair of stone lions. The church is laid out on a typical early Christian basilica plan, with a narthex and atrium, a wide central nave and lateral aisles, transept and semi-circular apse with ambulatory. Alterations were made by the Lombards in the 10th century, and by the Normans between the 11th and 13th centuries. Two Corinthian columns stand in the nave.
In the right aisle is the Hauteville Tomb, in which five members of the Norman Hauteville family are buried. Their bones, previously buried separately, were gathered into a single monument in the mid-16th century by Agostino Gorizio Barba da Novara, bailiff of the Knights Hospitaller of St. John of Jerusalem.
In the left aisle is the tomb of Aberada or Alberada of Buonalbergo, who married Robert Guiscard in 1053 but was repudiated by him for the Lombard princess Sichelgaita of Salerno. Aberada's son by Guiscard, Bohemond I of Antioch, hero of the First Crusade, died in Bari in 1111 and buried in Canosa di Puglia.
Construction of L'Incompiuta began in the last quarter of the 11th century. Use was made of materials from monuments of various civilizations, including the Roman, Lombard and Jewish. The layout is unusual for Italy, and French in conception; it shows similarities to that of the cathedrals of Aversa and Acerenza.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.
