Ērģeme castle served as a powerful fortress for the protection of the Livonian Holy Order eastern border and as a castle-front for the Cēsis castle of the Livonian Holy Order master. The castle was mentioned in 1422 but it was built already around year 1320 under the ordinance of the Order master Gerhard von Jocke. Masters used castle as a storehouse, point of support and shelter for the night. Planning of the castle is clearly legible. Nowadays still quite impressive castle ruins with the round corner tower in the height of two stories can be viewed.
Outside stone wall of the castle forms a regular quadrangle (it is so-called convent type castle) with two big fortification towers. Moats filled with water were around the castle. Drawbridge united the castle-front with the central part. Castle of Ērģeme was in the district of the master of Holy Order, ancillary castle of the Komturei of Cēsis. In 15th century castle was significantly rebuilt. In 1575 Ērģeme was conquered by the Livonian duke Magnuss who sold the castle to Polish in 1578. In 1621 Swedish king Gustav Adolph occupied the castle and in 1625 it was loaned to the major-general de la Barre whose family owned the castle till 1795. In 1658 again castle was conquered by Polish. In 1670 fire started in the castle of Ērģeme and there are no data that afterwards castle was inhabited.
In the 5th of July 1702 during the Livonian war castle was blown up. Up to the 1853 castle was used as a grain storehouse of the parish. In 1986 castle ruins were conserved but works were not finalized, therefore castle ruins gradually are perishing. During the summer period cultural events take place in the open-air stage of the castle ruins.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.
