The Callanish VIII stone setting is one of many megalithic structures around the better-known (and larger) Callanish Stones (I) on the west coast of the isle of Lewis. This is a very unusual (and possibly unique) setting, with a semicircle of four large stones on the edge of a cliff on the south of the island of Great Bernera and looking across a narrow strait to Lewis. There is no evidence that the cliff has collapsed here and destroyed half of a complete circle - it would appear that a semicircle was the original intention. The tallest stone is nearly three metres high and the cliff-edge axis of the circle gives a diameter of about 20 metres.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
