The Tomb of the Eagles, or Isbister Chambered Cairn, is a Neolithic chambered tomb. First explored by Ronald Simison, a farmer, when digging flagstones in 1958, he conducted his own excavations at the site in 1976. Alerted by Simison, archaeologist John Hedges then mounted a full study, prepared a technical report and wrote a popular book that cemented the tomb's name.
16,000 human bones were found at the site, as well as 725 from birds. These were identified as predominantly belonging to the white-tailed sea eagle (Haliaeetus albicilla) and represented between 8 and 20 individuals. These were originally interpreted as a foundation deposit, however this interpretation has been challenged by new dating techniques. These reveal that the eagles died c. 2450–2050 BC, up to 1,000 years after the building of the tomb. This confirms growing evidence from other sites that the neolithic tombs of Orkney remained in use for many generations.
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.
