On top of the Říp Mountain is a romanesque rotunda of Saint George, which is one of the oldest buildings in the Czech Republic. This is mentioned for the first time in 1126, when Soběslav I, Duke of Bohemia, commemorating his victory at the Battle of Chlumec, where he defeated Holy Roman Emperor Lothair III, had the rotunda repaired and extended by the western circular tower. The rotunda's current appearance is the result of a purist reconstruction during the 1870s.
Inside the rotunda is a stone sculpture by contemporary Czech artist Stanislav Hanzík 'The Good Shepherd' from 1979, symbolising the arrival of Czech ancestors to the country and the beginning of Czech history there.
Near the rotunda is a tourist hut that was built in 1907 and still serves travellers today.
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.
