The Orto Botanico dell'Università di Pavia is a botanical garden maintained by the University of Pavia.
The garden was begun in 1773 as a successor to Pavia's earlier Orto dei Semplici (established 1558). By 1775 the garden was in use, with its first wooden greenhouses constructed in 1776. Nocca Domenico organized and expanded the garden 1797–1826, adding collections to exchange seeds and plants, and building a masonry greenhouse to replace the earlier wooden structures. The garden was extensively damaged in World War II, after which its greenhouses were relocated to the main building's south side.
Today the garden contains about 2000 taxa, with major collections of aquatic plants, conifers, hosta, hydrangea, magnolia, medical plants, peat bog plants, and a rose garden.
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.
