Schloss Pyrmont  Schloss Pyrmont, sometimes called Pyrmont Castle, was a "schloss" and the summer residence of the counts of Spiegelberg and counts of Waldeck-Pyrmont in the present-day German town of Bad Pyrmont. The current building dates to the 18th century and houses a museum. The "schloss" is part of Pyrmont Fortress ("Festung Pyrmont") which dates to the 16th century. Between 1526 and 1536, Count Frederick VI of Spiegelberg, overlord of the County of Pyrmont, built a fortress and "schloss" in valley of Pyrmont. He had experience in the construction of the fortress when he had reinforced Coppenbrügge Castle with walls and roundels. The fortress of Pyrmont was almost square in shape with a 40-metre-wide moat. The walls had casemates and a stone corner bastion, which echoes the Italian style of fortification. Access to the fortress was via a wooden bridge and later a drawbridge. Buildings were built inside the walls and, in the south-western area, the first "schloss" was built. Following the completion of the castle in 1536, it was garrisoned by Count Frederick VI, who resided in neighbouring Lügde. Later the "schloss" became the side wing of a larger "schloss", which his son, Philip, had built in 1557 in the Weser Renaissance style. According to tradition, this was a three-storey building with three wall dormers, similar to the Hämelschenburg. In addition, a tower was built for archiving documents. Philip died before the completion of the Renaissance "schloss". The building was completed by the husband of his sister, Hermann Simon of Lippe. Afterwards the counts of Lippe and the counts of Gleichen resided at the "schloss". In 1625, Count Hans Louis of Gleichen transferred the County of Pyrmont to the Count of Waldeck. During the Thirty Years' War, the succession dispute between the Bishopric of Paderborn and the Counts of Waldeck revived. For the Bishopric, troops under General Pappenheim, besieged the Pyrmont fortress in 1629, and its 400-man garrison surrendered after ten months. In 1633, Swedish troops recaptured the fortress, which was reconquered in 1636 by the Imperial Army. After being taken again by the Swedes in 1646, the fortress was handed over to the Counts of Waldeck in 1649.
