About 1300, a knight named Conrad von Tronecken is mentioned in document for the first time, and then somewhat later the Feste Troneck (fortification), which, however, is probably much older. Having been destroyed several times, by Cologne, Imperial and French troops, and then finally by an earthquake, only remnants of Dhronecken castle are left now, although a corner tower can still be climbed.
On the old castle's foundations in modern times, commercial buildings were built, and also a bigger, tall building – called the Schloss – which is today used as a forester's office. Also, a barn with beam construction serves as a community centre for the municipality of Dhronecken. The attractively laid-out castle gardens have been continuously planted and tended since 1985.
Below the castle is found a nature play area on both sides of a brook. A ford with stepping stones, a forumlike playing and gathering place on a slope, made out of mighty stone blocks, wooden footbridges over wetlands left in their natural state, playing houses, a suspension bridge and a monorail are the great attractions not only for children, but also for adults.
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.
