Frangokastello castle was built by the Venetians in 1371-74 as a garrison to impose order on the rebellious Sfakia region, to deter pirates, and to protect Venetian nobles and their properties. The Venetians named it the Castle of St. Nikitas after the nearby church. The locals, however, who never saw it in a positive light, contemptuously dubbed it Frangokastello, meaning the Castle of the Franks (i.e. Catholic foreigners), Castelfranco or Franco Castello.
The name eventually stuck and was adopted by the Venetians as well. According to local lore, when soldiers and builders arrived on the fertile plain to begin construction of the castle, the local Sfakians, led by six Patsos brothers from the nearby settlement of Patsianos, would destroy every night what the Venetians built during the day. Eventually, the Venetians were forced to bring in additional troops and the Patsos brothers were betrayed, arrested and hanged.
The castle has a simple rectangular shape, with a tower at each corner and the remains of a Venetian coat of arms above the main gate. The buildings within the walls, as well as the battlements, were constructed during the Ottoman Turkish occupation.
In 1770, the Cretan rebel Ioannis Vlachos, otherwise known as Daskalogiannis, was captured at Frangokastello by Turkish forces. He was later tortured and executed at Heraklion.
On 17 May 1828 a celebrated battle was fought at Frangokastello. Hundreds of Sfakiots and Epirotes led by Hatzimichalis Dalianis, a Greek patriot from Epirus attempting to spread the Greek War of Independence from the mainland to Crete, occupied the castle, but were besieged by the Turks and massacred. However, many of the Turks were then themselves killed by rebel ambushes launched from the local gorges. According to tradition, around the anniversary of the battle each May, shadows of the armed Cretan and Epirote soldiers who lost their lives there seem to march towards the fortress around dawn.
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.
