Dolmen de la Madeleine is an isolated dolmen located in a private field on the outskirts of the town of Gennes. It was probably built between 5 000-2 000 BC. There are a number of these sites in the area - but this one is said to be the largest. Like many of the larger dolmens, it has subsequently been re-used, in this case to house a bread oven. Although the bread oven is no longer in use as the dolmen is now a classified national monument, you can still see the remains of the oven.
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.
