Friedrichsfelde Palace

"The castle was built in 1695 as Rosenfelde Castle by order of the Electorate of Brandenburg's naval director Benjamin Raule. It changed owners several times, who had it rebuilt and refurnished according to their requirements. After the Second World War, the castle stood empty and neglected for years and was used as a training center in the meantime. It was only when the site was developed for the zoo that a new use was found for the dilapidated building as a stable. In the further course of development, it was actually supposed to be completely demolished; however, the East Magistrate decided to carry out an initial thorough renovation, which began in 1970. The richly carved staircase and the stuccoed banqueting hall from 1785 were preserved from the original interior. Due to a lack of original furniture, the rooms were furnished with pieces from other castles and manor houses. The castle was reopened to visitors for the first time in 1981."
