Slot Teylingen was presumably the family keep of the noble family Van Teylingen, from which the Van Brederode family directly descended. The castle was originally built to protect the north-south route in Hollandic territory. Later it became a forester's castle for the forestry of the counts of Holland, starting with William IV, count of Holland.
One of the best known inhabitants of the castle was Jacoba of Bavaria, who died there and her 4th husband Frank van Borssele. The drinking cups that have been dug up in the surrounding area are called Jacobakanntjes.
In present day only ruins are left of the castle. These ruins are, however, well preserved, existing out of a surrounding wall and a donjon which forms part of the wall, and which is partially surrounded by water. The wall dates from the start of the 13th century and the main building shortly thereafter. The castle was heavily damaged around 1570 in the Eighty Years' War, and partially restored after that.
Around 1675 the donjon was burned in a fire, after which decay set it, and parts were gradually demolished. The lands (and the ruins) were possessions of the province of Holland, and were nationalised in 1795. Shortly after the complex was sold, under the condition that the ruins would not be demolished.
In 1889 the ruins were donated by Jhr. Mr. W. van Teylingen back to the Dutch state, who still owns them. The ruins are under the care of the Rijksgebouwendienst (State's building service). At the end of the 20th century, the ruins were restored and the moat, which had been partially filled, was restored as well.
References:The Château du Haut-Koenigsbourg is situated in a strategic area on a rocky spur overlooking the Upper Rhine Plain, it was used by successive powers from the Middle Ages until the Thirty Years' War when it was abandoned. From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
