Lochranza Castle dates from the 13th century when it was owned by the MacSweens. In 1262, King Alexander III granted the castle and its lands to Walter Stewart, the Earl of Menteith. It is believed that Robert the Bruce landed at Lochranza in 1306 on his return from Ireland to claim the Scottish throne. By 1371, the castle was the property of Robert II. It is thought that at this time it was used as a royal hunting lodge.
During the 1490s, James IV used the castle in his campaign against the Lord of the Isles and the Clan MacDonald. In 1614 it was occupied by James VI and in the 1650s it was used by Cromwell. By 1705, Lochranza Castle was the property of the Hamilton family, after it was purchased by the Duchess of Hamilton. The Hamiltons had owned other estates on the Isle of Arran so eventually sold it to the Blackwood-Davidson family who used it as their principal seat. During the 18th century, the castle fell into disuse and was abandoned. The castle is now in the care of Historic Scotland.
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.
