The Giant's Ring is a henge monument at Ballynahatty, near Shaw's Bridge, Belfast. It dates from the Neolithic period and was built around 2700 BCE. It is near the Shaw's Bridge crossing of the River Lagan, a point which has been used as a crossing of the river since at least the Stone Age. The original purpose of the monument was most likely as a meeting place or as a memorial to the dead.
The site consists of a circular enclosure, 180 m in diameter and 2.8 hectares in area, surrounded by a circular earthwork bank 3.5m high. At least three of the five irregularly spaced gaps in the bank are intentional and possibly original. East of the centre of the enclosure is a small passage tomb with a vestigial passage facing west. There were reports of other tombs outside the enclosure, but there is no trace of these.
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.
