Once the largest city-fortress in the entire Republic of Venice, Zadar’s walls allowed it to retain more of its independence than most of its neighbouring cities, and meant that it was never captured by the Turks.
The most impressive gate of the walls was Land Gate - then the main entrance into the city - in the little Foša harbour, built by a Venetian architect Michele Sanmicheli in 1543. It is considered one of the finest monuments of the Renaissance in Dalmatia, and has the form of a triumphal arch with a central passage for wheeled traffic, and two smaller side arches for pedestrians. It is decorated with motifs such as St. Chrysogonus (Zadar’s main patron saint) on his horse, and the Shield of St. Mark (the coat of arms of the Republic of Venice). Previously, the area had been highly defensive, with a surrounding moat.
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.
