Verona was founded to the site of current Castel San Pietro. This green hill, crowned by cypresses, is home to the remains of the first settlements dating back to the 7th century B.C. From this magnificent vantage-point you can enjoy the view of the whole city spreading out, with its network of Roman Roads, its walls, tall towers and steeples and, if your eyesight is good, you can even make out part of the Arena and the Ponte Scaligero. The current castle was built in 1393, commissioned by Gian Galeazzo Visconti.
At the foot of the hill flows the river Adige, and, on the site of the first ford (used for centuries) the suggestive Ponte Pietra (roman Stone Bridge). At the top of the hill stands the Austrian Fortress erected in the 19th century and which can be reached by a stair-way near the Roman Theatre. He pre-existing castle, on which the fortress rests and from which it takes its name, was erected towards the end oh the 14th century, during the first reign of the Visconti. Napoleon’s troops in 1801, and later the Austrians demolished much of this medieval structure.
The palace is not open to the public.
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.
