The church and monastery of the Augustinian hermits in Erfurt was built around 1300. Martin Luther, the famous Augustinian monk, was admitted to the monastery on 17 July 1505. The Augustinian Monastery pays tribute to Martin Luther with a new exhibition. The Lutherzelle (Luther's cell) can be visited as part of the exhibition. Since 1988 the monastery has been used as an ecumenical conference centre and a memorial to Luther.
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.
