The Vatican Gardens have been a place of quiet and meditation for the popes since 1279 when Nicholas III moved his residence back to the Vatican from the Lateran Palace. Within the new walls, which he had built to protect his residence, he planted an orchard (pomerium), a lawn (pratellum) and a garden (viridarium).
Created around the hill of Saint Egidio (where the Palazzetto del Belvedere is located today) and the courtyards of the Vatican Museums, this was to be the first garden in the Vatican. However, should you visit the Vatican Gardens today you would begin by viewing a totally different area from that first orchard, one located in a more recent addition to what is now Vatican City State. It is there that larger and more recent gardens have been planted, covering together with the original garden about half of the 44 hectares of Vatican City.
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.
