The Villa of the Mysteries (Villa dei Misteri) is a well-preserved suburban Roman villa on the outskirts of Pompeii, southern Italy, famous for the series of frescos in one room, which are usually thought to show the initiation of a young woman into a Greco-Roman mystery cult. These are now probably the best known of the relatively rare survivals of Ancient Roman painting. Like the rest of the Roman city of Pompeii, the villa was buried in the eruption of Mount Vesuvius in 79 and excavated from 1909 onwards (long after much of the main city). It is now a popular part of tourist visits to Pompeii, and forms part of the UNESCO World Heritage Site at Pompeii.
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.
