Lövstad Castle has its origins from the 15th century, but the present building was erected by Axel Lillie in the 17th century. It came to the von Fersen Family through Hedvig Catharina De la Gardie (who was the heir of her mother Hedvig Catharina Lillie) and to the Piper Family through Sophie Piper, who was sister to count Axel von Fersen.
The interior is intact since 1926, when the last owner died. Lövstad is today a museum open to the public with guided tours. There is a café and a restaurant at the castle.
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.
