The fortified old city of Durrës was built by the Byzantine Emperor Anastasius I (r. 491–518), who came from Durrës. At the time, Anastasius made the city one of the most fortified cities on the Adriatic. The ancient walls were devastated in an earthquake in 1273, and had to be extensively repaired.
Currently the medieval walls stand at nearly 4.6 meters in height and the three entrances of some of the fortification towers are preserved in nearly one-third of the original length of the city walls. The castle was reinforced with several guard towers by the Republic of Venice and during the period of rule in Albania by the Ottoman Empire the wall was reinforced.
On 7 April 1939, Albanian patriots fought the Italian invasion of Albania. In Durrës, a force of only 360 Albanians, mostly gendarmes and townspeople, led by Abaz Kupi, the commander of the gendarmerie in Durrës, and Mujo Ulqinaku, a marine official, tried to halt the Italian advance. Armed only with small arms and three machine guns, they succeeded in keeping the Italians at bay for several hours until a large number of light tanks disembarked from the latter's naval vessels. After that, resistance diminished and within five hours the Italian forces had captured the entire city.
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.
