The Castlelaw Hill Fort is the remnant of a stronghold of the Iron Age. When it was occupied the site consisted of three earthwork ramparts, ditches and timber palisades. The fort contained a Souterrain for the storage of agricultural produce. V. Gordon Childe undertook excavations at Castlelaw in 1932–33. The work focused on the rampart, and showed that it consisted of a clay and timber filling, faced by stone.
The fort commands views over the Forth and Lothian. Traprain Law and Berwick Law, both significant centres of power in the Iron Age, are visible from the site.
The fort is maintained by Historic Environment Scotland as a scheduled monument. Access to the site is free but, since the area is an active sheep pasture, dogs should be kept under control. The site also neighbours an army firing range and so care should be taken not to pass into the area marked by red flags.
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.
