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:Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
