Boskednan stone circle is a partially restored prehistoric stone circle near Boskednan, 6.4 kilometres northwest of the town of Penzance in Cornwall. The megalithic monument is traditionally known as the Nine Maidens or Nine Stones of Boskednan, although the original structure may have contained as many as 22 upright stones around its 69-metre perimeter.
The stone circle once probably consisted of 22 granite blocks, from which 10 still survive. Six stones stand upright, one sits half a metre out of the ground, the others remain lying in the soil. The stones are all about 1 m high, the highest measure approximately 2 m and stand to northern edge of the circle. The stone circle originally described a circle with a diameter of approximately 22 m. The stone circle may have belonged with the nearby barrow to an extensive cult district.
Stone circles such as that at Boskednan, were erected in the late Neolithic or in the early Bronze Age by representatives of a Megalithic culture.
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.
