Carra Castle dates to around the early 14th century. The castle lies in a field near the coast and the harbour of Cushendun, known as Murlough Bay. The site had once been used during medieval times as a children's cemetery.
The castle was once occupied by Irish king Shane O'Neill, and Sorley Boy McDonnell was held as a prisoner here in 1565. In 1567, two years after being defeated by O'Neill, the McDonnells entertained him in Castle Carra during two days of hunting and feasting. However, on the third day, 2 June, during a quarrel, they stabbed O'Neill to death to avenge their earlier defeat and sent his head to the English representatives of Queen Elizabeth in Dublin Castle.
In 1585, Donnell Gorm MacDonnell was besieged by the English,; his father, Sorley Boy landed near the castle and drove off the besiegers. Around 1730, it was known to have been occupied by the Lynch family. Today the castle is in ruins and overgrown with ivy.
The house has the characteristics of a hall house, but its outside dimensions are that of a tower house. What remains are the ruins of a 16th-century square tower house built over a Mesolithic flint working site.
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.
