The Guaita fortress is the oldest of the three towers constructed on Monte Titano, and the most famous. It was built in the 11th century and served briefly as a prison. It is one of the three towers depicted on both the national flag and coat of arms. It was registered as one of the World Heritage Sites in 2008.
Guaita was rebuilt in the second half of the 15th century and in the 16th century has been covered with a sloping roof. It is called the Rocca Guaita and, within its solid walls, protected by double walls (the external wall with merlons and truncated towers at the corners), the population found refuge during sieges.
The upper entrance door, which can be reached by a staircase, is protected by a small wooden construction of 1481. The courtyard contains some pieces of artillery from the Second World War: two mortars, a gift from Vittorio Emanuele II, two 75mm canons fired by the Guardians of the Rocca during national festivities, a gift of Vittorio Emanuele III.
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.
