Fort De Roovere was part of the West Brabant Dutch Water Line. It is an earthen fort that goes through a wall (the Ligneweg) and is connected to Fort Pinssen. The fort is open from the ‘back’, and the ‘front’ consists of two bastions. The fort has a dry moat and the banks are overgrown with trees. In 1747, during the Austrian War of Succession (1740–1748) the fort was under siege by the French. This siege has been extensively documented. Eventually, the fortress Bergen op Zoom fell and the siege was abandoned.
Over the years, the de Roovere fort has fallen into major disrepair. It has only recently been restored through contributions. In addition, a bridge was built to access the fort across its moat. The designers felt it would be inappropriate to build a bridge over the moat, so instead, they decided to construct a partially submerged bridge, rendering it practically invisible. The bridge has taken on the name 'The Moses Bridge,' as it appears to have divided the moat's waters. This design allows people to cross virtually undetected at water level: only a few bobbing heads are usually visible. Its construction is entirely of wood waterproofed with foil.
A foundation has been established, Friends of Fort de Roovere, whose goal is to make sure the fort is not forgotten. In the middle of 2010, extensive renovation of the fort began with the removal of the undergrowth and a deepening of the old moat so that the fort could be more easily recognizable as such. The clearing of the area led to many local protests. Remarkably, very little to no interest was paid toarcheological research as there should be traces of the French siege nearby. Local amateurs with metal detectors still regularly findcannonballs there, which must have come from the siege.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.
