The New Fortress of Corfu is a Venetian fortress built on the hill of St. Mark in Corfu. The current buildings which exist within the fortress were built by the British during their rule of the island (1815–63).
In the aftermath of the first great Ottoman siege of Corfu in 1537, the Venetians developed plans to expand the fortifications of the city. Venetians built the New Fortress at the hill of St. Mark to further strengthen the defences of the outer city of Corfu and to act as the focal point of the new fortifications. The exact dating of the structure is not established but accounts vary between 1576 or 1577-1588, and 1572-1645.
The sea defences of the New Fortress were destroyed by the British when the British protectorate came to an end and Corfu was united with Greece in 1864. Under the same agreement, the Avrami and Vido island forts were also destroyed. When the latter fort was demolished, the explosion was so strong that it broke house windows on the Corfu side of the sea channel.
At the top of the castle there is a stone building which was used for defence and a brick building which in modern times functions as the headquarters of the Naval Station of Corfu. The Venetian fortifications were later expanded by the British and the French to help defend against a possible Turkish attack. Its fortifications included 700 pieces of artillery with range estimated as far as the Albanian coast.
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.
