Château de Fleckenstein was built on a sandstone summit in the Middle Ages. The first record of the castle dates from 1165. It is named after the Fleckenstein family, owners until 1720 when it passed to the Vitzthum d'Egersberg family. In 1807, it passed to J-L Apffel and in 1812 to General Harty, baron of Pierrebourg. In 1919, it became the property of the French state.
The rock and the castle have been modified and modernised many times. Of the Romanesque castle, remains include steps cut into the length of the rock, troglodyte rooms and a cistern. The lower part of the well tower dates from the 13th or 14th century, the rest from the 15th and 16th. The inner door in the lower courtyard carries the faded inscription 1407 (or 1423); the outer door 1429 (or 1428). The stairwell tower is decorated with the arms of Friedrich von Fleckenstein (died 1559) and those of his second wife, Catherine von Cronberg (married 1537).
The 16th-century castle, modernised between 1541 and 1570, was shared between the two branches of the Fleckenstein family. Documents from the 16th century describe the castle and a watercolour copy of a 1562 tapestry shows its appearance in this period. Towards the end of the 17th-century Fleckenstein was captured twice by French troops. In 1674 the capture was achieved by forces under Marshall Vauban, who encountered no resistance from the defenders. The castle was nevertheless completely destroyed in 1689 by General Melac. Major restoration work was carried out after 1870, around 1908 and again since 1958.
The castle is located between Lembach to the south and Hirschtal to the north, only about 200 meters to the southeast of the present French frontier with Germany, at a height of about 370 meters above mean sea level. The castle, is accessible by road or via hiking trails.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
