Arnot Tower is a ruined 16th-century castle. The current building dates from c. 1507, though fortifications were present c. 1400. The castle has four storeys and a vaulted basement. It was built by the Arnot family who have records dating back to 1105. David Arnot of Fyfe was one of 2000 noble landowners required to swear allegiance to King Edward I of England in 1296. Nicol Arnot Arnot was a loyal supporter of King Robert the Bruce. Robert Arnot was killed in the battle of Flodden in 1514. The Arnots abandoned the old tower around 1700.
In 1760 local poet Michael Bruce wrote a poem about the true story of a love affair between an Arnot daughter and a Balfour of nearby Burleigh Castle. The families were in a feud, and it is believed the daughter of Arnot eloped to Burleigh Castle.
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.
