Tully Castle was built for Sir John Hume, a Scottish planter. During the Irish Rebellion of 1641, Rory Maguire set out to recapture his family’s lands. He arrived at Tully Castle with a large following on Christmas Eve, and found the castle full of women and children. Most of the men were away. Lady Mary Hume surrendered the Castle, believing that she had assured a safe conduct for all in her care, but on Christmas Day the Maguires killed 60 women and children and 15 men, sparing only the Humes. The castle was burnt and the Humes never went back.
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.
