Around 800 AD, a chapel is said to have been built on the site of current Saaleck Castle. The origins of the castle remain unclear. It was first mentioned around 1030 by a historian from the nearby Homburg, which was being extensively expanded at the time.
Significant expansions were made in the 13th century. Abbot Heinrich von Erthal (1249–1261) completed the fortifications, adding ditches, walls, and battlements. The neck ditch was deepened, and the shield wall was reinforced. Over the following centuries, the castle was continuously worked on. Even Ulrich von Hutten once paid 50 guilders to renew a wooden bridge over the southern neck ditch.
Originally, Fulda's southernmost stronghold played an important role in the region. The castle was strategically located and was significantly strengthened during the time of Abbot Marquard I.
After the Thirty Years' War, Salentin von Sintzig rebuilt the castle as his retirement residence. According to his reports, the castle was in a very ruined state at the time, with large stones being taken away by locals for their own construction purposes. From 1644 to 1667, he meticulously rebuilt the entire complex. Before the Peasants' War, the castle had lost its military importance and had fallen into ruin. It had not suffered significant damage from wars or fires until the outbreak of the war, when it was suddenly occupied and devastated by rebels.
About 100 meters below the castle lies the upper end of the chapel's way of the cross from the Altstadt Monastery.
Today, the castle, or Schloss Saaleck, is protected as a landscape-defining historical monument.
The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
