Torrylin Cairn is the remains of a Neolithic chambered tomb. The cairn has been interfered with by stone robbing and later dumping of field stones and its original shape and size are uncertain. The chamber is 6.7 metres long by about 1.2 metres wide with each compartment about 1.4 metres long. Torrylin Cairn is of a type found across south-west Scotland known as a Clyde cairn, of which a better preserved example can be found at Carn Ban, about 3 miles to the northeast. The tomb would probably have had a crescent-shaped forecourt, framed by a façade of slender upright stones.
Antiquarian excavations in the 19th century uncovered an elongated burial chamber, divided into four compartments. Only the innermost compartment was intact. It contained the remains of six adults, a child and an infant. Beside them lay a flint tool and a fragment of pottery.
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.
