The ruins of Bichishausen Castle are picturesquely located in the Große Lautertal valley. It was erected in the early 13th century, but the tower was demolished already around 1300. Heinrich Treisch von Buttlar modified the castle as residence in the 16th century, but it was left to decay after his wife died in 1545.
The freely accessible ruins offer a unique panoramic view of the valley, the river Große Lauter and the village of Bichishausen, but are rarely visited by tourists. In the small castle complex you will find an outer castle, a core castle with a palace and the courtyard with the foundations of a keep. A tip for visitors who want to climb the castle ruins in wet weather or snow: You can reach the very top via the built-in stairs, but the steel stairs can be very slippery in bad weather.
References:The Chapel of St. Martin is the only completely preserved Romanesque building in Vyšehrad and one of the oldest in Prague. In was built around 1100 in the eastern part of the fortified outer ward. Between 1100 and 1300, the Rotrunda was surrounded by a cemetery. The building survived the Hussite Wars and was used as the municipal prison of the Town of the Vyšehrad Hill.
During the Thirty Years’ War, it was used as gunpowder storage, from 1700 to 1750, it was renovated and reconsecrated. In 1784, the chapel was closed passed to the military management which kept using it as a warehouseand a cannon-amunition manufacturing facility. In 1841, it was meant to be demolished to give way to the construction of a new road through Vyšehrad. Eventually, only the original western entrance was walled up and replaced with a new one in the sountren side. The dilapidating Rotunda subsequently served as a shelter for the poor.
