Varignano Roman Villa is an ancient Roman residence in Varignano, now a frazione of the town of Porto Venere. Its site is marked by an archaeological museum.
Its first construction phase dates to the 1st century BCE and it mainly consisted of a house surrounded by a farm linked to olive oil production. The site is beside the Seno del Varignano Vecchio, overlooking the sea, near the santuario delle Grazie and, to the north-east, the Fortezza del Varignano.
Its main area - the pars urbana - and the productive area - the pars fructuaria - were separated by a courtyard used for 'torcularium' or pressing olives for their oil. The owner's residence was single-storey with atria paved with mosaics, living rooms and bedrooms. Its olive oil processing area contained two presses and a 'cella oleario' were active until the 1st century AD. At that period olive oil production shut down and the vilicus underwent a major rebuild, with the construction of a set of heated rooms and private frigidaria, whose cistern is considered as almost unique among similar buildings in northern Italy. This residence was then active until the 6th century.
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.
