Porta Siberia is a massive gate, dating back to 1551-53. It was the work of Galeazzo Alessi and once formed part of the 16th-century walls. Its name derives from 'cibaria' (foodstuffs), for it was through this gate that the city's produce passed, both on arrival from the sea and departure towards other ports in the Mediterranean.Once used as a customs area, after the Old Port was restructured it was turned into a museum devoted to the painter and set designer Emanuele Luzzati, housing temporary exhibitions by the Genoese artist and by leading contemporary illustrators.
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.
