The history of Orisberg mansion dates back to 1676, when the mayor of Vaasa, James Rossi, with his partners were licensed to establish and ironworks to Orisberg. There were 11 owners, until in 1783 a Stockholm merchant and shipowner, Bengt Björkman, acquired Orisberg and several other ironworks in Finland. Due the nobility family name later was changed to Björkenheim.
Captain Lars Magnus and Lovisa Wilhelmiina Björkman host of the manor as a pair and they begged permission to hire a priest and build their own church. These permits were granted and the mansion was an independent parish for 40 years from 1828 to 1868. Orisberg church, bell tower and the parsonage was designed by architect Carl Ludvig Engel.
In addition to managing a small church pastor's duties included work as a teacher. Because there were not yet elementary schools the wealthiest people sent their children to school in Orisberg even over long distances.
Today Orisberg is one of the recreation centers run by Logos Ministries in Finland, an organization within the Lutheran Church of Finland. It offers services for visitors in the summer time. There are cabins for rent, well equipped camping area for tents and caravans, cooking facilities, sauna by a small lake. A café in an old vicarage serves delicious meals. The place still belongs to the manor Orisberg (Björkenheim), which is still a working farm.
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.
