The Callanish II stone circle is one of many megalithic structures around the better-known (and larger) Callanish Stones (I) on the west coast of the isle of Lewis, in the Outer Hebrides, Scotland.
The stone circle consists of thin standing stones arranged in the shape of an ellipse measuring 21.6 by 18.9 metres. Five of the stones are standing and two have fallen. The stones vary from 2 to 3.3 metres in height. A slab, 1.4 metres, long lies in front of the western stone, pointing towards the centre of the circle. The stone circle surrounds a cairn with a diameter of 8.5 metres.
When one metre of peat was removed from the site in 1848, four holes were noticed, three grouped in an arc at the northwest, a fourth at the south-west. Wood charcoal found in them suggests that they formed an earlier timber circle about 10 metres in diameter.
References:The Villa d'Este is a 16th-century villa in Tivoli, near Rome, famous for its terraced hillside Italian Renaissance garden and especially for its profusion of fountains: the extraordinary system contains fifty-one fountains and nymphaeums, 398 spouts, 364 water jets, 64 waterfalls, and 220 basins, fed by 875 meters of canals, channels and cascades, and all working entirely by the force of gravity, without pumps. It is now an Italian state museum, and is listed as a UNESCO world heritage site.
Tivoli had been a popular summer residence since ancient Roman times due to its altitude, cooler temperatures and its proximity to the Villa Hadriana, the summer residence of the Emperor Hadrian I.
The Villa was commissioned by Cardinal Ippolito II d'Este (1509-1572), second son of Alfonso I d'Este, the Duke of Ferrara and grandson of Pope Alexander VI, along with Lucrezia Borgia.
