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: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.
