Because of the autumn storm, Königstein Fortress in Saxon Switzerland, one of the most popular excursion destinations in the Free State, closed its gates on Thursday morning.
The reason is strong wind gusts, as the administration announced.
Visitors who were on the plateau 240 meters above the Elbe were sent down.
In the early afternoon, the situation is to be checked and a new decision will be made, said an employee on request.
Königstein - Königstein Fortress was first mentioned in 1241 as "lapide regis" in the Elbe Sandstone Mountains.
The once medieval Bohemian royal castle was later a monastery, state fortress, court festival venue, art depot and prison.
