The Chapel of St Non is located on the coast near St David's. Held by tradition to mark the birthplace of St David, the ruin cannot be accurately dated but is unusual in that it is aligned north-south rather than the usual east-west. Near to the ruined chapel is a retreat, a modern chapel and a holy well.
The ruin is thought to be on the site of St Non's house and to be one of the oldest Christian buildings in Wales. In medieval times the chapel was one of the main sites visited by Christian pilgrims. Following the Protestant Reformation, pilgrimages stopped and the chapel was converted into a house before being used as a garden.
A large stone standing in the corner of the ruined chapel, inscribed with a cross within a circle, is known as St Non's Cross. The stone was found in the same field as the chapel and is either a grave or an altar stone. The stone is dateable to the 7th to 9th century, but there is no firm evidence that it originally came from the site.
In the chapel field there are a number of standing stones which may be evidence of an Iron Age settlement. It is possible that the chapel was built within an original pagan circle of standing stones.
A holy well close to the chapel was thought to have healing properties, and to this day visitors throw coins into the well for luck.
A modern chapel was built near the ruin in 1934 by Cecil Morgan-Griffiths, a solicitor from Carmarthen, using stone from ruined local chapels.
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.
