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:
From its origin as a small stronghold built by the ancient Illyrian tribe Dalmatae, becoming a royal castle that was the seat of many Croatian kings, to its final development as a large fortress during the Ottoman wars in Europe, Klis Fortress has guarded the frontier, being lost and re-conquered several times. Due to its location on a pass that separates the mountains Mosor and Kozjak, the fortress served as a major source of defense in Dalmatia, especially against the Ottoman advance, and has been a key crossroad between the Mediterranean belt and the Balkan rear.
Since Duke Mislav of the Duchy of Croatia made Klis Fortress the seat of his throne in the middle of the 9th century, the fortress served as the seat of many Croatia"s rulers. The reign of his successor, Duke Trpimir I, the founder of the Croatian royal House of Trpimirović, is significant for spreading Christianity in the Duchy of Croatia. He largely expanded the Klis Fortress, and in Rižinice, in the valley under the fortress, he built a church and the first Benedictine monastery in Croatia. During the reign of the first Croatian king, Tomislav, Klis and Biograd na Moru were his chief residences.
In March 1242 at Klis Fortress, Tatars who were a constituent segment of the Mongol army under the leadership of Kadan suffered a major defeat while in pursuit of the Hungarian army led by King Béla IV. After their defeat by Croatian forces, the Mongols retreated, and Béla IV rewarded many Croatian towns and nobles with 'substantial riches'. During the Late Middle Ages, the fortress was governed by Croatian nobility, amongst whom Paul I Šubić of Bribir was the most significant. During his reign, the House of Šubić controlled most of modern-day Croatia and Bosnia. Excluding the brief possession by the forces of Bosnian King, Tvrtko I, the fortress remained in Hungaro-Croatian hands for the next several hundred years, until the 16th century.
Klis Fortress is probably best known for its defense against the Ottoman invasion of Europe in the early 16th century. Croatian captain Petar Kružić led the defense of the fortress against a Turkish invasion and siege that lasted for more than two and a half decades. During this defense, as Kružić and his soldiers fought without allies against the Turks, the military faction of Uskoks was formed, which later became famous as an elite Croatian militant sect. Ultimately, the defenders were defeated and the fortress was occupied by the Ottomans in 1537. After more than a century under Ottoman rule, in 1669, Klis Fortress was besieged and seized by the Republic of Venice, thus moving the border between Christian and Muslim Europe further east and helping to contribute to the decline of the Ottoman Empire. The Venetians restored and enlarged the fortress, but it was taken by the Austrians after Napoleon extinguished the republic itself in 1797. Today, Klis Fortress contains a museum where visitors to this historic military structure can see an array of arms, armor, and traditional uniforms.
