The Mên-an-Tol is a small formation of standing stones in Cornwall. It consists of three upright granite stones: a round stone with its middle holed out with two standing stones to each side, in front of and behind the hole. When seen at an angle from one side, the stones form a three-dimensional '101'.
The site probably dates from the late Neolithic-early Bronze Age (approx. 2500-1500 BC) as do the other stone circles in West Penwith, and was probably used for ritual and ceremonial purposes.
The two side stones are both about 1.2 metres high. The westernmost stone was moved and brought into a straight line with the other two stones sometime after 1815. The holed stone is roughly octagonal in outline. It is 1.3 metres wide and 1.1 metres high; the circular hole is 0.5 m in diameter. The only other holed stone in Cornwall of this type is the Tolvan holed stone which can be seen in a garden near Helston.
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.
