Attavyros is the highest mountain on the island of Rhodes. It rises to a height of 1,215 m. In Greek mythology Althaemenes founded an altar to Zeus Atabyrios on the mountain. He was said to have chosen the site as the only point on Rhodes from which his homeland of Crete could be seen. The remains of the sanctuary can be seen near the summit.
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.
