Pfeffingen Castle is one of the largest castle ruins in the canton Basel-Land. In the area around Aesch and Pfeffingen existed originally a Franconian royal court. However, no remains have preserved from this time. In 1135 Notker von Pfeffingen was mentioned for the first time, which was probably related to Count von Saugers.
At the end of the 12th century, the Pfeffingen castle fell to the Count of Thierstein. In 1212 a family of Schaffner von Pfeffingen, who lived in the castle, was mentioned for the first time. In the mid-13th century the castle was comprehensively rebuilt. At this time, the curtain wall and the large residential tower were built. In 1335, the Bishop of Basel besieged the castle without success.
The great earthquake of Basel damaged Pfeffingen castle in 1356. When the Counts of Thierstein-Pfeffingen tried to expand their rule, it led into conflict with the city of Basel, whereupon Basel army successfully besieged the castle in 1376 and burned it down. The castle was restored after it.
In the 15th century Pfeffingen was conquered several times in wars between Austrian Habsburgs and Swiss armies (during the Old Zürich War). The castle, heavily damaged by the numerous wars, could not be maintained. In 1571, a new residential building was built as a replacement for the old residential tower, and a tower-defended gate and a bridge were built in the eastern part of the complex.
In the Thirty Years' War in 1637 the castle was occupied by Swedish troops under Bernhard of Saxe-Weimar and only eleven years later left in very poor condition to the bishop. Around 1750 the castle was finally abandoned by the Blarer family of Wartensee, who moved to the Aesch castle. Afterwards, a hermit lived temporarily in the castle. In 1761, the castle was auctioned on demolition and then fell rapidly.
After preparatory work in 2011 and 2012, construction work began in May 2013, overseen by ZPF Ingenieure. As the lime mortar that is used here can only be worked with when there is no frost, i.e. in the warmer half of the year, the work will take around six years. As the largest and most seriously damaged part of the ruins, the residential tower is to be reconstructed first. Here, there is a particular focus on sealing the coping and structurally securing unstable sections. The goal of the work is to repair the existing damage and to preserve the historical structure.
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.
