Wanda Mound is a tumulus assumed to be the resting place of the legendary princess Wanda. According to one version of the story, she committed suicide by drowning in the Vistula river to avoid unwanted marriage. The mound is located close to the spot on the river bank where her body was found. Archaeological studies, conducted on site in 1913 and in mid-1960, did not provide any conclusive evidence of the mound's age and purpose.
The mound base, some 50 metres in diameter and its height is 14 metres. Unlike the other three mounds in Kraków, this one is not located on a natural hill.
The first written record of the mound comes from the 13th century. Within a mile of the mound-site in 1225 a monastery was built by the bishop of Kraków, Iwo Odrowąż, called the Mogiła Abbey, which is still active today. In 1860 it became a part of Austro-Hungarian fortifications, pulled down only in 1968-1970. In 1890 a monument designed by Jan Matejko was erected at the top.
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.
